Abstract
Abstract A pulse signal conditioning circuit. Repetitive pulse signals can be sharpened and freed of accompanying, unwanted noise manifestations by means of a network of steering diodes and constant current diodes feeding a comparator circuit producing sharp, uniform pulses.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
172 words
Means for providing a clean sharp pulse signal of constant voltage from an input signal containing a series of repetitive pulses along with unwanted noise signal components; including a parallel network having an input terminal and an output terminal and consisting of: a first channel including a constant current diode and a steering diode connected to pass electrical signals from the said input terminal to the said output terminal; a second channel including a constant current diode and a steering diode connected to deliver signals from the output terminal to the input terminal; a comparator circuit connected to deliver a single pulse signal in response to applied inputs exceeding a pre-established threshold value; means connecting the said output terminal to the input of said comparator circuit; a multi-vibrator connected to deliver in response to a pulse input, a constant voltage signal for a pre-established duration which is a minor fraction of the pulse-to-pulse spacing of the said input signal; means connecting the comparator circuit output to the input of the said multi-vibrator.
