8.7.2 Total Receive Path Response
8.7.3 Receiver DC Offset Subtraction
The 73M1x66B provides a method to improve audio quality by reducing unwanted DC offset from the
receiver signal path in A-law or μ-law compression modes. This method requires that a signal path
calibration be performed. This calibration is benign to the performance of the device and is only required
after an initialization or device reset sequence. Receiver DC offset calibration can only be executed when
the device is on-hook and not in linear mode, otherwise the process will disturb signal quality.
