FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -An analog-to-digital converter (ADC) is used to convert an analog signal such as voltage to a digital form so that it can be read and processed by a microcontroller. Most microcontrollers nowadays have built-in ADC converters. It is also possible to connect an external ADC converter to any type of microcontroller.

Detailed explanation-2: -ADCs follow a sequence when converting analog signals to digital. They first sample the signal, then quantify it to determine the resolution of the signal, and finally set binary values and send it to the system to read the digital signal. Two important aspects of the ADC are its sampling rate and resolution.

Detailed explanation-3: -To convert an analog signal to a digital one, measurements must be sampled at a regular frequency. The sample rate must be at least twice its frequency. This approach is used in digital audio and video to reduce aliasing, or the production of a false frequency.

Detailed explanation-4: -Flash Conversion When an ADC (analog to digital converter) has a comparator that fires for each decoded voltage range, it is not as a direct conversion ADC or flash ADC. A code for each voltage is generated from the comparator bank to a logic circuit for each voltage range.
