ECE 201 Lecture 20b Borja Peleato Waveform generation 1 Elapsed time We often use the time properties of dis charging of L or C to generate v t or i t waveforms In an RC or RL circuit all the voltages and currents are of the form x t x x t0 x e t t0 For a given k we can find the time t1 for which x t1 k by inverting that equation t1 t0 Loge k x x t0 x And similarly time elapsed between x t1 k1 and x t2 k2 is t2 t1 Loge k1 x k2 x 2 Problem 1 3 4 5 6 8 9 10 11 12 13
