Pulse frequency multiplier with output OR=gate - has input pulses producing sawtooth for applying to parallel triggers with variable references

摘要

The frequency multiplier has the positive-slope edges of the input pulses (UE) triggering amonostable flipflop (1) to produce triggering pulses for an integrator (2). These triggering pulses reset the integrator so that its output is a sawtooth. - The sawtooth is applied to the inputs of a series of triggers (3) each connected at its output to a monostable flipflop (4). The outputs of the flipflops are combined in a multiple-input OR-gate (6) to produce the frequency-multipled output (UA). The reference inputs of the triggers are connected to the sliders of potentiometers (5).
