... Mixers · Recorders General Description The HT8950/HT8950A are single chip CMOS LSI voice modulator ICs which provide seven steps to shift the fre- quency of an input voice, producing a dramatic change in the output. The HT8950/HT8950A provide two special effects: Vi- brato and Robot. The Vibrato effect is generated by al- ternating the frequency of an input signal up and down at a rate of 8Hz ...
