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.
