This simulation demonstrates a signal sampling circuit using a MOSFET as a switch. The green waveform represents the original continuous sine wave input, while the red waveform shows the sampled version of the signal. A clock pulse of 1 Hz is applied to the MOSFET gate, causing it to periodically connect and disconnect the input signal to the output. As a result, the output consists of discrete samples of the sine wave at intervals defined by the clock frequency. This illustrates the fundamental
