WebKnow how to analyze a circuit’s response to a periodicwaveform The periodic square-wave shown on the top is applied to the circuitshown on the bottom.1. Derive the first four nonzero terms in the Fourier series thatrepresents the steady-state voltage vo if Vm=210π V and the periodof the input voltage is 0.2πms. WebIn theory a square wave has an instantaneous rise and fall. But it has a dwell time based on the frequency. Lets take a 1 hz square wave. The signal goes from zero to 100% [1] in an instant. Then will remain at 1 for 1/2 of the wave length or 500ms. Then it goes negative to -1 and remains there for 500ms.
