	Ring modulation - Wikipedia, the free encyclopedia
		Ring modulation is an audio effect performed by multiplying two audio signals, where one is typically a sine-wave or another simple waveform.
		It is referred to as "ring" modulation because the analog circuit of diodes originally used to implement this effect took the shape of a ring.
		Ring modulators were used by the BBC Radiophonic Workshop to produce the distinctive voice of the Daleks in the television series Doctor Who.

	Ring modulator (Site not responding. Last check: 2007-10-08)
		A Ring modulator is a type of electronic circuit mostly used in synthesizers.
		This process of ring modulation produces a signal rich in overtones, suitable for producing bell-like or otherwise metallic sounds.
		The name "ring modulator" comes from the fact that the circuit of diodes used to implement it looks like a ring.

	Harmony Central®: Effects Explained: Ring Modulation
		Modulation means that we are changing some aspect of a tone, such as it's amplitude, frequency, or phase.
		In the ring modulator, we are using amplitude modulation (more specifically, suppressed-carrier modulation) which is implemented simply by multiplying two signals.
		The ring modulator's output alone may be totally unsuitable depending on one's tastes, but the sound can be smoothed a bit by simply mixing in the original instrument sound.

	EXPLORING ANALOGUE: The mighty Modular Part 1
		Modular synths that sported ring modulators were the ARP 2600, the EMS VCS3 and Synthi series (A, AKS, 100) and the Roland 700M and 100M, to mention but a few.
		Ring modulation was not a feature of Moog synths but I believe that one Harold Bode was a chum of Bob's and he made a wonderful (but expensive!) unit which Moog made available.
		Using a ring modulator patched as shown in the diagram, with the same signal feeding both inputs, allows you to create upwards octave splits, where the sum is exactly double the input frequency (see main text for a full description).

	Modulators and Hybrids
		They are the ring modulator, which uses four diodes and two transformers to make a very good balanced modulator, and the hybrid transformer, used for separating propagation directions in converting a duplex circuit to a four-wire circuit, and vice versa.
		The principle of the ring modulator is shown at the left.
		It is very inconvenient to build a ring modulator from vacuum diodes, but the circuit was made practical with the invention of solid-state rectifiers, the first of which was the copper-oxide rectifier.

		Modules are usually small parts of a synth, ie a modular synth is a synth built up of modules, modules would be segments like, low frequency oscillators, filters, ring mods, and can be so so many other things.
		As for ring modulators, the gonkulator and the frequency analyser aren't the only ones out there, many people have used them and you probably missed it, like jeff beck, he "tunes" his to the song he's playing and lets it get wild.
		ring modulation has to do with how signals are combined, like how 2 oscillators could combine their simple sound waves to make a new, complex tone with lots of harmonics.

		actually alot of "ring modulators" now-a-days are not actually ring modulator, but they are balanced amplitude modulator which sounds similar.
		and the modulator is generally fixed in frequency (unlike say a DX7, where the modulator's frequency can change to always stay in relation to the note being played, and thus produce more "musical" tones)) and will thus give you a more "mathematical" sound.
		ring modulation multiplies 2 signals together and subtracts the origionals from the resulting signal.

	The FREQue II Ring Modulator from DACS
		Although ring modulation is a simple process and has been around for years, all designs have been plagued by excessive leakage of the unprocessed audio and modulation signals into the processed output.
		The output of a ring modulator is the algebraic sum of the sum and difference of the audio signals' frequencies, not voltages.
		The FREQue II is a better ring modulator with even more versatility now and, like the original FREQue, has the least amount of leakage of the modulator signal at the output of any I have tried before.

		As seen by their use of the wedding ring, ancient Romans weren't the most sentimental of people, and the early version of their "engagement ring" were thought to have carved keys on them.
		In short, it is clear that the giving of a ring in honour of a union, betrothal, and marriage has been going on since ancient times, and although it may not always have been as glamorous and romantic as it is today, it was still a way of exchanging a contract of betrothal or marriage.
		Thankfully, today's wedding bands and engagement rings are not made of hair, grass, plants or twine as they may have been in ancient times, but of beautiful metals set with stunning gems, such as platinum, titanium, white gold, gold, sapphires, diamonds, rubies and emeralds.

	EXTREME EFFECTS
		Ring Modulators are intriguing devices designed to process two input signals in such a way that the sums and differences of the input frequency components are generated while the input signals themselves are suppressed.
		Processing percussion via a ring modulator can be good — use a pitched synth sound for the other input and you'll end up with a metallic, pitched drum part that could form the basis of an experimental electronic song or dance track.
		The way this is achieved is that the frequency spectrum of the modulator is continually monitored using a bank of frequency-spaced band-pass filters, and the information used to control the gains of a corresponding bank of band-pass filters in the carrier's signal path.

		Now, connect a cable from the 'voltage processor' (constant module) to the Modulation depth input of the Ring Modulator and away is the unwanted breakthrough of the sinewave sound.
		This is because since both the carrier and the modulator are at the same frequency, X + X = 2X which gives us one sideband in which the original sound, being doubled, is raised by one octave; and another sideband in which, since X - X = 0, the original sound is left unchanged.
		The Ring Modulator module not only affects the pitch and timbre of sounds, it can also be used for all kinds of amplitude effects like echoes, gating, tremolos, etc.

		Valued for their ability to transform ordinary source signals into wilder, inharmonic timbres, ring modulators were considered an essential part of the earliest electronic-music studios.
		A ring modulator, or balanced amplitude modulator, is a circuit that modulates two separate input signals, the carrier (c) and the program (p), generating sideband frequencies at a single output.
		With two ring modulators, two built-in oscillators, CV inputs, internal frequency modulation, and a frequency shifter, the FREQue provides an excellent hybrid instrument for the analog synthesist.

		A ring modulator outputs the product (Multiplication X and Y) of the signals at inputs X and Y. It's similar to a VCA, but whereas a VCA only responds to positive voltages at the inputs (2-quadrant multiplication), the ring modulator responds to both positive and negative voltages (4-quadrant multiplication).
		Ordinary amplitude modulation will output the original carrier frequency fC as well as the two side bands (fC - fM, fC + fM) for each of the spectral components of the carrier and modulation signals - but ring modulation cancels out the carrier frequencies, and just lets the side-bands pass to the output.
		A ring modulator is used for the production of bell-like sounds, alien voices, or just to produce new timbres.

		A ring modulator should be a four quadrant multiplier, hence people with analog systems in general need something dedicated for this.
		The other way arounf though, depending on the design of the ring modulater it might be possible to use the ring modulator as a VCA (one of the input signals hould be DC coupled so it can act as the control input).
		This non perfectness applies mostly to the "classical" implementation using a "diode ring" (that is where the name ring modulater comes from) and two transformers, but "modern" IC analog four quadrant multipliers are not exactly free of artifacts either.
