Waveform Multiplier

A-137

1. Introduction

Module A-137 is a Voltage Controlled Waveform Mul-

tiplier. The basic idea of a wave multiplier is to multiply

the waveform of an incoming signal (e.g. triangle from

a VCO) within one period. This leads to additional

harmonics. The period and consequently the pitch of

the signals remains unchanged - in contrast to fre-

quency multiplication e.g. with the PLL module A-196.

The A-137 works as a kind of "

inverse low pass filter

i.e. it adds a lot of harmonics to the incoming signal.

Consequently the best results are obtained with signals

that contain none or only a few harmonics (e.g. triangle

or sine waveforms). The A-137 can be used with signals

rich in harmonics too (e.g. saw) but the effect is not as

remarkable as for triangle or sine waves.

The A-137 is a very sophisticated wave multiplier that

offers much more features, more controls and more

waveform manipulations than other wave multipliers

available so far. In addition all four parameters are both

manually adjusted and controlled by external volta-

ges:

• Multiples: number of waveform multiplications

• Harmonics: adds more harmonics similar to the re-

sonance/emphasis control of filters

• Folding Level/Symmetry: value and symmetry of

the upper/lower folding level
