fifth harmonic. Assume the filter has Q=100. (Hint: The filter transfer function is Фо T(s) = ལུ W + where =1/√LC and Q=aCR.)/n15.11 For the oscillator circuit in Fig. 15.5, assume that v, is an ideal square wave of frequency a, and amplitude V volts. Recalling that the Fourier series for a square wave is 4V 1 1 [sin()+sin(3)+sin(5 of) +...] find the third harmonic component of the output vo as a percentage of the fundamental component.
