a linear amplifier with a gain of 40 dB is overdriven, resulting in the output shown in 3-19

a) sketch the amplifier output frequency spectrum up to 5kHz. b) the output signal is driving a low pass filter whose exact frequency response(spectrum) is shown in 3-19b. Sketch the filter output frequency spectrum, Vo(f). c)Sketch accurately the filter output time waveform as seen on an oscilloscope. d) Write the Fourier series expression for the filter output waveform. e) calculate the total harmonic distortion(THD). f) How could the distortion be eliminated?(a little thought and analysis will show that mere filtering will not work)
