Electronic devices rely on signals to communicate, and these signals come in two forms: analog and digital. Analog signals are continuous signals that vary over time, while digital signals are discrete signals that are either on or off. Converting analog signals to digital form is essential for processing and transmitting signals in electronic devices. This process is accomplished using Analog to Digital Converter Circuits
An ADC circuit samples an analog signal at regular intervals and converts it into a digital signal. The conversion process involves two steps: sampling and quantization. During the sampling step, the analog signal is measured at specific intervals, and its amplitude is stored in a memory buffer. The quantization step involves converting the sampled analog signal into a binary number.
