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...
