Quizplus · Accepted Answer

A reset input signal can be used to quickly discharge the capacitor and reset the peak detector circuit in preparation for another input signal. This ensures that the circuit is ready to detect the next highest value input signal. Bypass capacitors are used to filter out unwanted noise and stabilize power supply, but they do not help in discharging the capacitor in peak detector circuit. Similarly, a small load resistor can be used to balance the input impedance of the circuit, but it does not aid in quickly discharging the capacitor. A virtual ground can be used in some circuits to create a stable reference voltage, but it is not effective in discharging the capacitor in peak detector circuit.
