Digital-frequency-doubler


Posted on Jul 12, 2012

The circuit doubles tbe frequency of a digital signal by operating on botb signal edges. Each transition causes exclusive-OR gate IC1 to produce a pulse, which clocks flip-flop IC3 after propagating through buffers IC2C and IC2B. Ifyou remove capacitor Cl, tbe circuit produces narrow output pulses.
