Pulse Code Modulation (PCM): A digital modulation technique where an analog signal (green waveform) is sampled at regular intervals using a clock signal (purple waveform), quantized into discrete steps (orange staircase waveform), and encoded into binary. The setup includes waveform generators, a sampling and encoding block, and a 7-segment display to show the binary output in decimal form, visualizing the real-time digital representation of the analog signal. #ElectronicsEducation #electronics

This simulation illustrates the sampling and quantization stages of Pulse Code Modulation (PCM). The green waveform is the analog input signal, the blue waveform is the sampling clock that triggers measurement of the input, and the red waveform is the quantized staircase output representing the sampled values. The binary form of each sample is shown on the 7-segment display. While this demonstrates the core steps of PCM conversion, it does not display the actual serial PCM bitstream, which would
