Generate Filters coeffitients using *.m file

I have made a FIR filter without filterDesigner tool

Unrecognized function or variable 'I'.

Fs = 48000; % Sampling rate
T = 1/Fs;
L = 320;
t = (0:L-1)*T;  
x = sin(2*pi*1000*t) + 0.5*sin(2*pi*15000*t);

h = fir1(28, 6/24);
y = filter (h, (1), x);

How can I generate the list of filter coeffitients?

Or I should convert it somehow to *.fda file (don't know)?

h contains your filter coefficients, so what do you want exactly?

I mean to generate a C header file

[Mathieu NOE]

your code works fine

what's the problem ?

Fs = 48000; % Sampling rate
T = 1/Fs;
L = 320;
t = (0:L-1)*T;  
x = sin(2*pi*1000*t) + 0.5*sin(2*pi*15000*t);
h = fir1(28, 6/24);
y = filter(h,1,x);

plot(t,x,t,y);

[Star Strider]

If I understand your question correctly, the filter coefficients are the ‘h’ vector.

Also, use filtfilt for the best results, not filter. This applies even to zero-phase FIR filters.

Just search for how to generate a C file
