Oscilloscope converter

Posted on Nov 13, 2012

The monolithic quad operational amplifier provides an inexpensive way to increase display capability of a standard oscilloscope. Binary inputs drive the IC op amp; a dual flip-flop divides the scope`s gate output to obtain channel selection signals. All channels have centering controls for nulling offset voltage
