(a) A periodic waveform vat) is applied to the input of a network. The output v,(t) of the network is v,(t) = t[dv{t)/dt], where t is a constant. What is the transfer function H(w) of this network ? (b) A periodic waveform vat) is applied to the RC network shown, whose time constant is 1= RC. Assume that the highest frequency spectral component of vAt) is of a frequency f 1/t. Show that, under these circumstances, the output v,t) is approximately v,t) [dvft)/dt]. v, (t) vott) Figure P1.5-1
