I am debugging AGC . I set slow attack mode, full table and set the outer threshold high is -1dBFs、inner threshold high is -2dBFs、inner threshold low is -3dBFs、outer threshold low is -4dBFs. But the BBP captured a distorted signal.
And I changed the threshold is -7dBFs、-8dBFs-、9dBFs、-10dBFs. The BBP captured a normal signal.
The digital gain is 0dB.
I am confused why get a distorted signal.
