Cascadable analog-value comparator

摘要

Two analog voltages, on one of which an adjustable squarewave voltage is superimposed, are conducted to a comparator and compared. The adjustable squarewave voltage is conducted to the comparator via a transformer. When the two analog voltages are equal, a squarewave voltage appears at the output of the comparator which can be used as clock pulse for other analog-value comparators which can be added.
