Assume the switch shown in figure P2 is ideal and opens in zero time at t=0[s]. The current and voltage conventions shown must be used in the analysis to receive any credit. b) Use your answer to part 2(a) above and the relationship between the inductor current, iL(t), and the inductor voltage, VL(t), shown below in equation P2 to compute VL(t) for t≥0.

Rewrite the network function as a product of recognizable 1st order responses. 2. Name each response (gain, LP, HP, diff., integrator, augmented diff.) and provide a numeric value for the respective critical frequency. • Clue: Integrators and differentiators are uniquely specified by their "unity gain” frequency the frequency at which the magnitude response becomes 1 or 1 dB. 3. Sketch the corresponding magnitude response on a dB-per-decade (log-log) scale.arrow_forward
