10–81 Pulse Conversion Circuit The purpose of the test setup in Figure P10–81 is to deliver damped sine pulses to the test load. The excitation comes from a 1-Hz square wave generator. The pulse conversion circuit must deliver damped sine waveforms with ζ

ω0 > 10 krad=s to 50-Ω and 600-Ω loads. The recommended values for the pulse conversion circuit are L = 10mH and C = 0:1 μF. Verify that the test setup meets the specifications.

(Hint: Compute the voltage across the load for an input signal equal to a unit step function, u t ð Þ, and then again for a negative unit step function, −u t ð Þ.) Note that the output of a square wave generator is the sum of a series of step functions.
