![]() ![]() ADC Provides a link between the analog world of transducers and the digital world of signal processing and data handling.When signals are in digital form they are less susceptible to the deleterious effects of additive noise as compared to analog signals.Microprocessors can only perform complex processing on digitized signals.Digital signals only have two states i.e. ![]() The output of a microphone, the voltage at a photodiode or the signal of an accelerometer are the examples of the analog values that need to be converted so that a microprocessor can work with them.Īnalog signals are directly measurable quantities. For example, a sound picked up by a microphone into a digital signal. An analog-to-digital converter (ADC) is a system that converts an analog signal to a digital signal.
