General Description7vj嘉泰姆

The SC7072Bis a single-chip CMOS LSI designed for voice changer, which can transpose or distort one7vj嘉泰姆

voice into another voice by encoding the input audio signals in normal speed and transmit the output audio7vj嘉泰姆

signals with unusual speed. That is accomplished by sampling the input audio signals into digital signals and re-7vj嘉泰姆

arranging the digital signals to generate different voice from the user’s normal voice. The SC7072B includes7vj嘉泰姆

microphone amplifier to amplify voice signal and noise reduction circuit for reducing environment noise.7vj嘉泰姆
