Generating analog waveforms An analog-to-digital convertor (ADC) is an electronic circuit whose digital output is proportional to its analog input Effectively it "measures" the input voltage, and gives a binary output number proportional to its size The input range of the ADC is usually determined by the value of a voltage reference Sep 6, 2012 · ADC (Analog to digital converter) forms a very essential part in many embedded projects and this article is about interfacing an ADC to 8051 embedded controller. The analog part of the circuit needs to remember the analog voltage at the exact time of the sampling (usually done by charging a capacitor for a finite amount of time) Once that value is remembered, the ADC needs to determine (quantize) what the corresponding digital value to that voltage is. ADCs play a crucial role in modern technology by transforming actual analog signals from the real world into digital data that computers and digital systems can comprehend and handle. Analog signals are continuous in time and amplitude, while digital signals are discrete in time and amplitude.
