- * \brief Audio DC analog test main file
- *
- * Audio analog test verifies the functionality of ADC and DAC available on
- * audio daughter card. During this test, data received from ADC will be
- * sent to DAC. There are two instances of DAC and ADC available on
- * audio daughter card. One ADC supports 4 analog channels and one DAC
- * supports 8 analog channels. Data received from one DAC shall be sent
- * to both the ADCs making 8 channel Rx/Tx. Each DAC should be validated
- * separately.
