Abstract
Abstract A gated pulse generator produces on output pulse for every period in which an input signal is continuously in a particular state for longer than a minimum gating interval. If the input signal changes state within the minimum gating interval, no output pulse is produced.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
212 words
A gated pulse generator comprising: first switching means comprising an amplifier having an output terminal, an inverting input terminal, and a non-inverting input terminal with the output terminal switching from a first output state to a second output state when a signal at the inverting input terminal reaches a first threshold level; capacitor means connected to the inverting input terminal of the first switching means; second switching means comprising an amplifier having an output terminal, an inverting input terminal, and a non-inverting output terminal; third switching means comprising an amplifier having an output terminal, an inverting input terminal, and a non-inverting input terminal; said output terminals of said second and said third switching means connected to the capacitor means for controlling the charging of the capacitor means as a function of an input signal; a reference potential applied to the non-inverting input terminal of the second switching means and the inverting input terminal of the third switching means; said input signal being applied to the inverting input terminal of the second switching means; and the output terminal of the first switching means being connected to the non-inverting input terminal of the third switching means for causing the first switching means to switch between said output states, whereby an output pulse is provided.
Claim 2
Dependent Claim
212 words
A gated pulse generator comprising: first switching means comprising an amplifier having an output terminal, an inverting input terminal, and a non-inverting input terminal with the output terminal switching from a first output state to a second output state when a signal at the inverting input terminal reaches a first threshold level; capacitor means connected to the inverting input terminal of the first switching means; second switching means comprising an amplifier having an output terminal, an inverting input terminal, and a non-inverting output terminal; third switching means comprising an amplifier having an output terminal, an inverting input terminal, and a non-inverting input terminal; said output terminals of said second and said third switching means connected to the capacitor means for controlling the charging of the capacitor means as a function of an input signal; a reference potential applied to the non-inverting input terminal of the second switching means and the inverting input terminal of the third switching means; said input signal being applied to the inverting input terminal of the second switching means; and the output terminal of the first switching means being connected to the non-inverting input terminal of the third switching means for causing the first switching means to switch between said output states, whereby an output pulse is provided.
Claim 3
Dependent Claim
33 words
