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 v0. Determine the peak
amplitude of the sound wave (in decibels) if v0 = 5VRMS.

Estimate the maximum peak magnitude of the
sound wave in order that v0 not contain any saturation
effects of the op-amps.
