Flip-Flop Applications

Frequency divide-by-2
Patch the D input to the NOTQ output. Patch your signal to the CLOCK input and listen to the Q output. The Q output will be one octave down from the CLOCK input. To divide by 4, just patch the second flip-flop the same way and apply the Q output of the first to the CLOCK input of the second. The series can be continued indefinitely into more Logipac modules. This is the principle used to derive all the lower octaves from a top-octave generator in virtually all electronic organs.

Start something / Stop something
Patch the "something" to the Q output. Patch your start signal to the SET input and your stop signal to the RESET input. The flip-flop will act as a latching switch.

Synchronize one signal to another (logical sample-and-hold)
Take any old random signal and bring it into rhythm with a reference by patching the signal into the D input and the reference into the CLOCK input. The Q output will be a reference-synchronized version of the input signal.

Bring it into the analog world
Patch the Q output into a lagger or low-pass filter. Patch the output of the lagger back to the RESET input. When the flip-flop is SET or CLOCKED high, the lagger will automatically RESET the flip-flop after a delay. This creates a one-shot circuit. Try the synchronization trick described above at audio rates.

These examples represent the simplest things you can do and demonstrates the power of the anything-to-logic input circuit. The analog and digital worlds can marry seamlessly, creating endless chaos in the process. Try listening to the parity of 3 oscillators.

But Captain, that's not logical!
