I am using ADAU1761.
The digital signal from the master controller is sent to ADAU1761 and DSP in ADAU1761 need to do some processing
on the signal.
Now I want to get the digital data output before DAC and compare the output data of ADAU1761(before DAC) with the output of the master controller. I just want to know the data transfer is correct or not.
question 1 How can I capture the digital data output before DAC output? I can not see the output data in Capture Window of Sigmastudio.
question 2 And, I think that the digital signal from the master controller should be transmitted through the serial data ports. Am I right?
question 3 How to eliminate the noise ? Especially the impulse noise in time domain. The duration of pulse noise is short, but the energy is large. Can I use the FIR to solve it ? Do I need to detecte the impulse noise first ? Or I just need to import FIR coefficient?
question 4 How can I get the BBE module to make it sound more clear. Could you give me a demo about how to program a microcontroller to emulate SigmaStudio to communicate with the SigmaDSP IC of ADAU1761 in a real production system.
