Question

A piezoelectric pressure transducer is equipped with a charge amplifier that generates analog voltage signals on the output. For further processing of these signals, an engineer is tasked to design an active, inverting, low-pass, 1st-order RC filter. The filter should have a cutoff frequency 6 kHz and a static sensitivity 5.5. The engineer can use only the following components: type-741 operational amplifiers, resistors of any values, and 0.5-microfarad capacitors.
(a) Draw the circuit diagram of the active, inverting, low-pass, 1st-order RC filter:
(b) Determine values of circuit components of this filter:
(c) For this filter at 90 kHz frequency of input signals: calculate the magnitude ratio, and the attenuation in Decibels.
