vhdl code for hamming window

Hi,

I never said sin/cos LUT but LUT for your hamming figures.

It will help to know what actually you are upto when referring to hamming window. A window is just a set of scale factors that usually goes up then comes down.

It is used to modify filter response by scaling coeffs accordingly. It is also used to scale signals e.g. fft signal.

Matlab can give you values for various windows in the range 0~ 1. You need to decide how many taps you want. To scale your figures onto 16 bits(16,14):

winscaled = round(win*2^14/max(win));

after multiplication discard 14 LSBs from result.
