📌A Fourier series is a way to represent a periodic function as a sum of simple sine and cosine waves. It breaks down complex repeating patterns into basic trigonometric components, making it easier to analyze signals in fields like engineering, physics, and music. Each term in the series corresponds to a specific frequency, showing how much of that frequency is present in the original function. This method is especially useful in signal processing, where it helps to filter, compress, or reconst

This simulation demonstrates the complete signal journey from analog to digital and back. The input is a pure sine wave that passes through an Analog-to-Digital Converter (ADC), which samples and quantizes it into discrete digital steps. These stepped waveforms represent the binary-coded signal levels. The output of the ADC is then fed into a Digital-to-Analog Converter (DAC) that reconstructs the signal into a staircase waveform. Finally, the DAC output is smoothed using an active low-pass filt
