In TD-SCDMA telecomm, the phone sometimes output audio noise burst, that last about mille-second duration. It always happpens at almost the fixed time after the phone boots up. And the audio noise pattern is almost the same.
What is the root cause for that?
Is it because of the heat of the circuit?
Or spurs in the audio?
Or out-of-frame in telecomm?
