In the figure we have the way to implement a logic gate or (OR) with an LM393. The circuit must be powered by a symmetrical source and other operational ones can be used.
This circuit shows on the screen of an oscilloscope two signals alternately at a frequency that depends...
This circuit is from a Radio Electronics from August 1992. The transistor used allows the control of...
This circuit measures the strength of audio signals. We found it in an American publication from...
