Logic Pulses
Previous Up Next

 

Logic pulses are control pulses which might stop or start a process; the information is in the presence or absence of the pulse, the pulse itself being of fixed standardised width and height.

There are two standards for logic pulses - slow positive and fast negative. In normal gamma ray spectrometry systems it is most likely that logic pulses will be slow positive, 93W matched.
