Q. Let a square-wave voltage source having an amplitude of 5V, a frequency of 1 kHz, a pulse width of 0.5 ms, and an internal source resistance of 50 be applied to a resistive load of 100. A filter (inductance L) is inserted between source and load in order to reduce all the high-frequency components above 5 kHz. Determine (a) L of the low-pass filter, (b) amplitude spectra of VL and VS, and (c) vL(t).
