sampling low frequencies with 56311EVM

Started by Sameer . April 27, 2002
I am using 56311 EVM in sampling two 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
thanks in advance,
