In the figure we have 3 oscillators with logic gates that can be triggered by external logic signals. The circuits were found in the Radio Electronics magazine of April 1987.
This TTL bistable or flip-flop with the 7400 was found in an 80's publication. It is a didactic...
This circuit amplifies the signals of an operational amplifier with output values that depend on...
In the figure we have the simple way to use a low current switch or sensor to drive a high power...
