multiplicateur de fréquence

Starting with, for example, a music signal, or indeed any other type of sound, the following circuit can be used to generate a variety of interes-ting tonal effects. The input wave-form is sampled, and a small portion of the signal is stored in a memory. The signal is cycled repetitively through the memory before being read out again. In this way a new periodic signal which is obviously derived from, but completely different to, the original input signal is obtained.
