AUDIO_DITHERIZING_CIRCUIT_FOR_DIGITAL_AUDIO_USE

Published:2009/7/9 1:47:00 Author:May | From:SeekIC

By adding a small amount of noise to a signal to be digitized (about 0.7 bit): where: n=# of bits. For example, 8 bits and 2 V p-p would be 0.0055 V. This circuit uses a transistor (Q1) and an amplifier (Q2 and U1) to generate controls the noise signal，R11 controls the noise injection and R12 controls the gain of the system.
