Re: FDA binary Vs decimal representation

Hai,

If i do scaling on the filter coefficients to convert the real values
into integer values whether the precision get affected?

regards,

Hai,

I generated the filter coefficients  with fixed point number and
stored as binary form and got the following:

1111010110011011
0100101101001001
0100101101001001
1111010110011011

whose decimal value are
-0.081207275390625
 0.588165283203125
 0.588165283203125
-0.081207275390625

which one is high precision representation?whether both will give same
response?

I have to represent the following output in binary?wat is the command?
 output = conv(h, Inp);

regards,
faza
