Web8 jun. 2015 · An analog to digital converter ( ADC, A/D, or A to D) is a device that converts a continuous physical quantity (usually voltage) to a digital number that represents the quantity’s amplitude.In block diagram form, it can be represented as such: Fig.1. A DAC, on the other hand, inputs a binary number and outputs an analog voltage or current ... WebOne class is analog filters. These filters can be designed to process time varying signals in their raw, real world (analog) form. The other class is digital filters. These filters are mathematical algorithms that operate on a digitized version of the analog signal.
