Abstract
A random signal isolation circuit connectable to a source of signal generation wherein signals of interest tend to occur at relatively closely spaced intervals, and noise signals tend to occur at random time intervals, including a first multivibrator trigger circuit which triggers on the falling edge of a received signal, and a second multivibrator trigger circuit which triggers on a rising edge of a received signal, the first multivibrator circuit being connected when triggered to enable the second multivibrator trigger to receive subsequent received signals. The first multivibrator trigger circuit is activated over a predetermined time delay, and at the end of the time delay disables the second multivibrator trigger circuit.
