Hi team,
Codec output differentially to left channel and Tone voice is output by HPR single terminal in right channel.
When Tone tone works alone, there will be obvious POP tone (Figure 2).
We try to delay PA_Mute for 60 ms after SDZ to avoid POP tone (the following delay waveform), and the differential output matches.
1) What is the relationship between the input signal of PA and enabling control signal mute and SDZ?
2) Why does delayed Mute eliminate POP tones? Are there any other optimization methods?
1. input signal 2. output signal
3. Delay mute signal, output can match
