		Data sources may be either digital (such as a computer) or analog (such as an electrocardiogram transmitter).
		This is in contrast to analog microwave, in which a digital bit stream would be converted to an analog carrier by a voice grade modem and then frequency shifted up to the appropriate carrier frequency.
		For example, in digital microwave systems, the radio frequency carrier is an analog signal, but its information modulation is derived from the digital signal.

		The digital environment is substantially less forgiving than it’s analog counterpart.
		Therefore, when a recording is finished in one application, it can be opened for processing or layback in another, with consistent levels, as there is no hardware flow in the chain that can alter the level.

	THE INS AND OUTS OF
		The classic problem is that recorded digital signal levels are pitifully low, while ludicrously high replay levels from the digital machine stress or overload the console returns.
		A quick and dirty trick for users of modular digital multitracks, though, is to switch the machine's output level from +4dBu to -10dBV, or to interface the outputs via the -10dBV unbalanced ports instead of the +4dBu balanced ones.
		The established alignment levels of digital systems, with +0dBu equating to -20 or -18dBFS were conceived with the best of intentions — basically to endow digital audio equipment with headroom comparable to analogue systems.
