A/D converter

(Analog/Digital converter) A device that converts continuously varying analog signals from instruments and sensors that monitor conditions, such as sound, movement and temperature into binary code for the computer. The A/D converter may be contained on a single chip or can be one circuit within a chip. See codec and sampling.

A/D Converters Are Everywhere
Every digital desk phone and cellphone has an A/D converter that turns electronic sound waves into digital PCM code. Every digital camera, camcorder and scanner uses A/D converters to transform the variable charges captured in CCD and CMOS chips into the binary pixel data that make up a digital image. See modem, DSP, CCD sensor, CMOS sensor, PCM and codec. Contrast with D/A converter.


A/D Converter
Widely used in consumer electronics, as well as industrial machinery, the A/D converter can be a chip or a circuit within a chip.

The AD converter allow selection of two sampling periods with arbitrary channels, contributing to a reduction of impedance adjustment parts in large-scale systems that require multiple sensors.

An ideal solution of this problem would be to control oscillator frequency in the AD converter according to [7].
It includes noise suppression circuits, filters and AD converter for two systems of tips (two tips or one tweezer can be used).

where [V.sub.cc] is the supply voltage; [O.sub.ADC] is output value of AD converter; N is the number of bits of AD converter (presently 10 bits that yields 1024 levels); [[bar.O].sub.CR] is the time-averaged value of output compare register OCR1A and [N.sub.CR] is the number of bits of this register (presently 16 corresponding to 65536 levels).
HYUGA II is designed with the capabilities of connecting to FMC boards with AD converter as well as connecting capabilities to Texas Instruments' ("TI") boards which have DA converters, thus making possible for analog signal connections and evaluating for wireless systems under more realistic environment.
