I am new to DSP and I am try to make a FIR filter threw the ScopeFIR SW.
I made some but I didn't see where I can see the phase of it at diffrente freq.
Is there a possibilty to make it or there is ather program or any written book where i can do the calculation on my on?

You might try MATLAB software....

They have a simple command to produce a Bode plot of a given system:

the command would be something like this:

z=tf('z',T) % T is your sampling time

g= 1+3*z^-1+6*z^-2+..... % g is your FIR filter, ^ means "to the power of"

bode(g) % will produce the gain and phase plot for
your filter

Hope this helps...
 

Hi

You can do both design and vertification using MATLAB.
fdatool is good tool in MATLAB which you can design filter, see phase and amplitude response.
And you can simulate fixed-point effect on filter responses.
