Question

A sinusoidal sound (pressure) wave p(t) impinges

upon a condenser microphone of sensitivity S

(mV/kPa). The voltage output of the microphone vs is

amplified by two cascaded inverting amplifiers to

produce an amplified signal v_{0}. Determine the peak

amplitude of the sound wave (in decibels) if v_{0} = 5V_{RMS}.

Estimate the maximum peak magnitude of the

sound wave in order that v_{0} not contain any saturation

effects of the op-amps.
