High Precision FIR-Filter for Audio-DSP in VHDL
	High Precision Audio Filter 32k Sample RAM 32k Coefficient RAM 48kHz x 24 Bit	A multi channel accumulation pipeline is used to perform continous operation on the incoming audio data by applying progammable filter coefficients and smoothing the audio data with a built in window. A modified Blackman-Harris-Window is used for this. Operation mode is 4 times oversampling using complex multiplication (I x Q). The audio data ist then resynthesized with smooting filter from out of the 4 pipelines. Thus both low deviation because of windowing and high bandwidth because of limited filter size are combined effectively. The spectral response ranges from 6Hz ... 20 kHz (-3dB) and 16 Hz ... 16 kHz (<1dB) operating well for common audio applications. Read about a high precision filter on a S3
