3. The modules and their functions ^
Use this input for the signal you wish to divide the signal of. Ideally, the input should be a rectangle wave having at least a 3Vp-p level, but you can also use a triangle wave or any other waveform as long as it is 3Vp-p, since the VTH (threshold level) is set at about 1V. Note, however, that regardless of the input waveform, the output waveform is always a rectangle or pulse wave.
Provides a rectangle or pulse wave output having a frequency half that of the input signal (the output pitch is one octave lower than the input).
Provides an output signal (rectangle or pulse) frequency 1/4 that of the input signal (the output pitch is two octaves lower than the input).
