hi,
i am at present working on a HDL project to carry out a type of
transform(Hilbert transform) on a set of 1-D data.
the process is simple.
the data is passed through a nine-tap low pass filter followed by
downsampling, then upsampling and then the 9-tap reconstruction
filter.
e.g. if the l.p.f co-efficients are h1,h2,hy3,h4,h5,h6,h7,h8,h9 then
o/
p of the low pass filtering is
x= h1*a(i) + h2*a(i-1)+...............+h9*a(i-9)
h1,h2.........,h9 are real nos. like 25/256,-1/32 etc.
hence division is achieved by right-shifting.
the reconstruction is similarly done
the same process is done simulteneously with a high-pass filter set.
PLEASE COULD ANY OF U BE KIND ENOUGH TO help me to make it
synthesizable.
