This simulation demonstrates a Track & Hold circuit where an analog signal is sampled and held using a switching device and a storage capacitor. When the control pulse is HIGH, the switch turns ON and the input sine wave is tracked — the capacitor charges to follow the instantaneous value of the signal. When the control pulse goes LOW, the switch turns OFF, isolating the capacitor. The stored voltage remains nearly constant, creating the stepped waveform seen in the simulation. The quality of th
