Lecture 23 figures 1 Fig. 23-1: Second-order circuits have an analog in a mass suspended from the ceiling on a spring. The differential equation governing the position x(t) is second-order and linear. Fig. 23-2a: The current or voltage for lossless oscillation. Fig. 23-2b: The current or voltage for underdamped oscillation. The sinusoidal oscillation is evident, but the amplitude decreases with time. Fig. 23-2c: The current or voltage for overdamped oscillation. The sinusoidal oscillation is not evident. Fig. 23-2d: The current or voltage for critically-damped oscillation. The waveform appears very similar to the overdamped case.
