Hi, I am using 56311 EVM in sampling two signals..one of my signals has frequencies well below 30 Hz..But I noticed that the codec is AC coupled with a high cutoff frequency of about 86Hz..What should I do? is shorting the serial capacitor C10 (connected to RING_IN) will solve this problem? I read about REFBUF signal of the codec..How does it affect this problem? Please tell me if you have any suggestions.. thanks in advance, Sameer
