Bidirectional integrator
First Claim
1. A bidirectional integrator for integrating an electrical signal comprising:
- first and second programmable pulse forming channels, each channel comprising means for forming a pulsed output signal having a pulse repetition rate which is a function of an input signal to said signal forming means, means for modifying said pulse repetition rate by a first factor selected from a continuous range of factors and a programmable circuit for multiplying and/or dividing said pulse repetition rate by a second factor selected from a plurality of discrete factors;
a bidirectional counter which is driven in one direction by the pulsed output signal from the programmable circuit of the first channel and in the opposite direction by the pulsed output signal from the programmable circuit of the second channel;
means for controlling the direction in which said bidirectional counter is driven; and
means for producing an output signal from said bidirectional counter.

Abstract
A bidirectional integrator is described comprising first and second programmable pulse-forming channels (20, 40), a bidirectional counter (60) and an output display (78). Each pulse forming channel provides means for making both continuous and discrete adjustments in the repetition rate of the pulses formed thereby. In the preferred embodiment, each pulse forming channel comprises an integrator (26, 46) for forming a pulsed output signal, means (24, 44) for varying the pulse repetition rate of the output signal by varying the input signal to the integrator, and a programmable digital divider circuit (30, 50) for dividing the repetition rate of the output signal by any power of two from one to 4096.
