It provides 7 steps to shift the fre- quency of an input voice, producing a dramati- cal change in the output. The HT8950 provides two special effects: Vi- brato and Robot. The Vibrato effect is generated by alternating the frequency of an input signal up and down at a rate of 8Hz. The Robot func- tion, on the other hand, converts an input voice into a Robot voice. Both effects can be selected depending on which pin is triggered, either ROB or VIB. For the output frequency level shifting, the chip provides 7 steps which can be selected from the two groups of pins namely, SW0, SW1 and SW2 for electronic direct selec- tion and ROB, TGD, TGU and VIB for push button selection. The HT8950 includes a built-in microphone am- plifier with an internal bias, an 8-bit A/D con- verter, a built-in SRAM as well as a current output type 8-bit D/A converter. The 8-bit A/D and D/A converters with a sampling rate of 8kHz ensures a high quality and high S/N ratio output voice. The chip provides an LED indica- tor which flashes with the volume of the input voices. It is offered in a 16-pin or 18-pin DIP package. 1 5th May ’98 |
