Dear all,

my problem straight away,

i am doing recursive frequency sampling filter design,

in matlab i design the filter coefficients, i gave the format long at the top
and received the 15 digits for representation after decimal point.

does this give the precision value for how many bits is it 64 or 32 bits i want
to do finite wordlength effects, in my project i hope u all might have worked on
this i will be expecting your valuable suggestions,
