The Codec and the FFT

Started by josalfe2002 July 23, 2002
Hi everyone.
Let me going to the point. I'm using the SDK libraries with my
codewarrior code. When I use the code, i simply use the "open"
funtion. My board (DSP56824EVM) uses a 13-bit codec. When I sample a
known signal (a sin signal) and try to plot it on and application
(for example: matlab) I see a different signal, and not the sin
Does anyone knows why this happend???...would it be that the 13-bit
codec make him work strange???...I say this because when I implement
an fft algorithm, i receive strange results.

Thanx for the help.
