Analogue-to-digital convertor

Fig. 3. Sketch of the hardware and software system used in the author s laboratory to investigate the electrode kinetics of electrochemical reactions. D.A.C are digital-to-analogue convertors, F.R.A. is a frequency response analyser, A.D.C. are analogue-to-digital convertors (used to switch devices), D.P.M is a panel meter, and NTWK is the university network serial connection to an Amdahl computer. The units I are the appropriate interfaces.

The values read by the transducers are passed via a 12 bit Analogue to Digital Convertor CADC) to the LSI 11 microcomputer which then determines the appropriate sector diagram for display on the Ramtek graphics monitor. 

Components of a modem gas chromatograph include a dedicated microcomputer with analogue-to-digital convertor (ADC) to digitize the detector signal, and software packages that perform the following functions (see also Section H) ... 

A 1024 multichannel analyser (Nuclear Data Model ND 100) incorporating an analogue to digital convertor (ND 500) displays the emitted spectrum on an oscilloscope screen. By adjusting electronic markers the count within the Kcx iodine peak can be read on the alphanumeric display on the upper part of the screen.
