*15.29 Assuming that the diode-clipped waveform in Exercise 15.9 is an ideal square wave and that the resonator Q is 30, provide an estimate of the distortion in the output sine wave by calculating the magnitude (relative to the fundamental) of
(a) the second harmonic
(b) the third harmonic
(c) the fifth harmonic
(d) the rms of harmonics to the tenth
Note that a square wave of amplitude V and frequency ω is represented by the Fourier series
(a) 0; (b) 4.17 × 10−3; (c) 1.39 × 10−3; (d) 4.5 × 10−3 or 0.45%
