CP161

 

CP161

The CP161 module contains four electronic comparators. These are used to compare two voltages - if the difference of these signals is greater than zero the comparator outputs a 1, otherwise it generates a 0.

These output signals may be used to control other circuits like relays, counters, flip flops, etc. One quite common example using a comparator is the absolute value function. The comparator is used to switch between a signal and its sign reversed negation.

The picture on the left shows the overall view of the quad comparator module CP161. On the right the plated metal fingers to which the patch cables connect to, can be seen. The electronics is spread over two single layer printed circuit boards.

The picture on the right shows a closeup of some of the electronics of the comparator.
