SOLVED: Design a waveform sampling and reconstruction circuit using ADC0804, DAC0800, 555 timer, and LM741 Op-amps. A 1 kHz, 5 V sinusoidal signal is sampled by ADC0804 with a sampling rate of 10 kHz. Then the digital output is connected to the input of DAC. Draw the circuit (specify the corresponding pin numbers of the chips) and the waveform on the output of the DAC. What circuit should be added so that the analog sinusoidal signal can be fully reconstructed?

This simulation illustrates the effects of different sampling rates on an analog signal using ADC (Analog-to-Digital Converter) and DAC (Digital-to-Analog Converter) circuits. The top purple waveform represents the original analog sinusoidal input signal at 100 Hz. The other three reconstructed waveforms — orange, green, and red — show the DAC outputs for high, medium, and low sampling rates, respectively: Orange waveform → Highest sampling rate: The output closely follows the original analog si

This simulation illustrates the effects of different sampling rates on a 100 Hz sine wave signal as it passes through an ADC–DAC system. The top (blue) waveform represents the original smooth sine wave. Below it, the green trace shows the reconstructed output when sampled at 1000 Hz — the waveform is closely matched to the original, with minimal distortion. The orange trace, sampled at 666 Hz, still follows the sine wave shape but with visible “stair-stepping” due to fewer samples per cycle. The
