cutoff frequency and FIR filter design
Hai,
suppose i am designing a LP or HP FIR filter using FDA tool for 128
taps wat is
the cutoff frequency value(range of values) given for communication
and multimedia applications??and which is the optimal FIR filter
method suited for that?
regards,
faz

... When using a lowpass FIR filter, with 100kHz sampling and 1kHz -3dB cutoff frequency, is there a minimum number of coefficients required for the filter to operate properly similar to a Nyquist minimum? ... I was thinking that there would be 100 or even 200 coefficients required since the cutoff frequency is 100 times lower than the sampling frequency so that the low frequency data can remain in the coefficient data long enough, but I am not sure if this is correct.. ...

... I have designed FIR filter in Altera FPGA. ... This FIR can have 2KHz or 4KHz cutoff frequency. ... Consequently, you could halve the sampling frequency, use the same FIR coefficients, and get pretty much what you requested. ... Note, however, that delays through the FIR filter will double, and if you are converting the digital stream back to audio, you may need to upsample it or filter it in the analog world more aggressively. ...
