An analog signal is continuous, but digital systems can only handle numbers. This simulation explains how signal reconstruction converts digital data back into a smooth analog waveform. On the left, the analog input is sampled by the ADC at a fixed clock rate. Each sample is converted into a digital code, shown by the stepped red waveform and the changing digital value display. This staircase shape is expected because the signal is now represented in discrete levels, not a continuous curve. Thes

This simulation demonstrates how varying the sampling rate impacts the fidelity of signal reconstruction in digital systems. At the top, a sine wave is sampled and reconstructed using different ADC (Analog-to-Digital Converter) and DAC (Digital-to-Analog Converter) clock rates. As the sampling rate decreases, the reconstructed signal becomes less accurate, showing clear distortion. This highlights the importance of choosing an appropriate sampling rate—typically governed by the Nyquist theorem—t
