This simulation illustrates the process of signal conversion from analog to digital (ADC), followed by digital to analog conversion (DAC) and filtering. The staircase waveform (blue) represents the DAC output, while the smooth curve (orange) shows the result after applying a low-pass filter, effectively reconstructing the original sine wave. This highlights how filters are essential in removing quantization noise and restoring clean analog signals from sampled data. #ElectronicsEducation #electr
