The IF102 is a double-pulse waveform generator (DPWG). Double pulse waveforms have a huge range of timbres, because of cancellation and reinforcement of the harmonics of the two pulses.
In the present module, the two pulses have equal widths, but the position and amplitude of the second pulse are variable. All three of these parameters are under voltage control, thus providing a wide range of dynamic timbral variations.
The circuitry is designed to be driven by a +/-V Saw wave, although other inputs can produce interesting results. A trimmer, located on the front panel, allows proper matching of the module to the input wave.
