PURPOSE: To reduce noise of an analog signal by converting a signal obtained by shifting a phase of a clock signal by 360/N degrees each into digital data and by calculating a mean value of N-sets of the digital data. CONSTITUTION: A clock signal S1 generated by a clock generator 2 is...
CHEM 411L Instrumental Analysis Laboratory Revision 1.0 Analog-to-Digital Conversion In this laboratory exercise we will construct an Analog-to-Digital Converter (ADC) using the staircase technique. In todays world ADCs can be obtained as Integrated Circuits on a single chip. Instead of simply purc...
Analog to Digital Conversion Method : There are several methods for Analog to Digital (A/D) conversion. We cover the examples of 'Flash Conversion', 'Successive Approximation Conversion' and 'Delta-Encoded Conversion'.

Quantization error and (assuming the ADC is intended to be linear) non-linearity is intrinsic to any analog-to-digital conversion.(量化和非线性是 A/D 固有的) There is also a so-called aperture error which is due to a clock jitter and is revealed when digitizing a time-variant signal (...
The first essential step in analog-to-digital(A/D) conversion is to sample an analog singnal.This step is performed by a sample and hold circuit,which samples at regular intervals called sampling intervals.The length of the sampling interval is the same as the sampling period,and the reciproca...
Analog to digital conversionis the process of transforming the signal from the analog domain to the digital domain. This process could take place at baseband, as is the case ofdirect conversion receivers, or at intermediate frequency (IF) or low IF depending on the requirements and consequently ...
From Analog to Digital Embedded systems often need to measure values of physical parameters These parameters are usually continuous (analog) and not in a digital form which computers (which operate on discrete data values) can process A Comparator is a circuit which compares an analog input voltage...
