	Baffle Step Compensation
		The so called "baffle step" is an increase in output from a loudspeaker as the size of the baffle becomes significant in terms of the wavelength of sound for a range of frequencies.
		The response ripples caused by this are extreme, but with most systems this is not an issue, since this would be a very unusual shape for an enclosure.
		The baffle step is easily compensated for where the speakers are mounted in trees or are in other (more sensible) outdoor environments, but becomes much more difficult as a normal listening room is introduced.

	Frequency Response
		The step response of a capacitor to a current step input is a voltage ramp output.
		Step response is one way of observing the effect of circuit self-behavior, which is called the transient response or natural response.
		= 90 degrees, the pole is imaginary and the response is a non-decaying sinusoid.

	Triggering an Oscilloscope to Capture a Step Response
		Triggering a scope to capture a step response is not hard as long as you are methodical in your procedure.
		Now try to capture the step response by timing its triggering so that it goes off while the screen scan is near the left-hand side of the screen.
		Note that the response fills most of the screen but that there is not a long flat-line section after the response.

	E12
		We used that fact to show that the impulse response is simply the derivative of the step response - this is probably the method you should use for the next week or two.
		Both the impulse response and the step response are zero-state responses (i.e., the initial conditions are equal to zero).
		Note that because there is a discontinuity in the step response, there is an impulse in the impulse response (the step response of the first example had no discontinuity).

	An Introduction To System Dynamics - Second Order Linear Systems
		Now, the question is "What does this have to do with the impulse response?" Earlier we noted that the effect of the impulse was to change the value of the derivative of the response immediately after the impulse occurred.
		Since the step is the integral of the impulse, the step response is the integral of the impulse response.
		We have seen how the step response changes when the damping ratio is varied, and the video shows pole location as the damping ratio is varied.

		That is, in step (9), the cwnd is reset to a value that avoids large packet bursts, and ssthresh is reset to the value of pipe_prev.
		Interworking with the CWV Algorithm (Step 10) An implementation of the Congestion Window Validation (CWV) algorithm [RFC2861] could potentially misinterpret a delay spike that caused a spurious timeout as a phase where the TCP sender had been idle.
		That is, the entire step 1B of the NewReno algorithm is obsolete because step (8) of the Eifel response algorithm avoids the case where three duplicate ACKs result from unnecessary go-back-N retransmits after a timeout.
