Resolution analog to digital converter

Understanding the Delta-Sigma ADC

Resolution and sampling rate are two important factors to consider when selecting an analog-to-digital converter (ADC). In order to understand these fully, concepts such as quantisation, and the Nyquist Criterion must be understood to a certain degree If we have a sampling time of T seconds, then the bitrate and the resolution are related as such: = Where r is measured in units of bits/second, T is measured in seconds, and n is measured in bits. Bandwidth . Bandwidth, denoted with a W, is the frequency range needed to transmit an analog or digital signal An analog signal is continuous in time and it is necessary to convert this to a flow of digital values. It is therefore required to define the rate at which new digital values are sampled from the analog signal. The rate of new values is called the sampling rate or sampling frequency of the converter. A continuously varying bandlimited signal can be sampled and then the original signal can be.

This AC voltage is its own analog signal, but one that can be passed through an ADC, or an analog-to-digital converter. This is where things start to get really fun. An ADC takes an analog signal that's continuous in both time and amplitude, and translates it into a series of numbers that most accurately represent its amplitude (how loud it is) at very specific points in time

Analog-to-Digital Converters (ADCs) transform an analog voltage to a binary number (a series of 1's and 0's), and then eventually to a digital number (base 10) for reading on a meter, monitor, or chart. The number of binary digits (bits) that represents the digital number determines the ADC resolution.
