Hi,
How to convert normalized frequency to logarithmic frequency.
I have magnitude response of filter,
x axis in normalized freq. 0 to 1(Sampling frequency).
I want to get the x axis in logarithmic frequencies.
How to do this in matlab?
Please any solutions for this

hello
you can easily create your x axis (frequency) vector by using logspace :
assuming you want N values :
% start_freq is the min normalized frequency
% stop_freq is the max normalized frequency
% Fs is the sampling frequency
freq = logspace(log10(start_freq*Fs/2),log10(stop_freq*Fs/2),N);
