This Simulation shows a Sample and Hold circuit in action. This type of circuit samples an analog input (blue waveform) at regular intervals and holds that sampled value for a period, producing a stepped output (orange waveform). The schematic illustrates a typical implementation using a MOSFET switch controlled by a 400 Hz pulse and a capacitor to store the voltage. An op-amp buffer isolates the capacitor to maintain the held voltage. This technique is widely used in analog-to-digital conversio
