Hi all,
Now,i want to know how to test the parameter above by using the tlv320aic1110evm?
1)Transmit idle channel noise, psophometrically weighted
I input signal the TXPGA gain= 0 dB, MIC Amp 1 gain = 23.5 dB,MIC Amp 2 gain = 6 dB,i want to know how to the noise at PCMO?
2)Transmit signal-to-distortion ratio with 1020-Hz sine-wave input
I input the MIC1N, MIC1P to PCMO at 3 dBm0,and how to the signal-to-distortion ratio at PCMO? And why the value is positive?
1)Receive noise, psophometrically weighted
The test conditions is PCMIN = 11010101 (A-law),what is meaning?and how do i input the 11010101 at the PCMIN?
2)Receive signal-to-distortion ratio
And how to the signal-to-distortion ratio?
THANKS !
BR!
