- Abstract:This paper designs a kind of filter used in audio processing of the DAC.Through the study of FIR filter parameters,this paper completed the over-sampling of the audio filter,so that over-sampling rate acheves 128 times.It also use the analysis tools in MATLAB fdatool to design filter.From the simulation waveform of it,the noise of signal ratio is achieved more than 100db,and it can better suppress pass-band noise.
