Hello, I was wondering if it was possible to write the code with subplots as I did. The idea of the program is to display a low-pass filter on the same window, with the index response at the top and the frequency response at the bottom. We vary N and display the curves in different colors on the same graph (the same subplot), whether for RF or stem.
Added to this is an error during program execution :
Error using stem (line 43)
X must be same length as Y.
Error in filtrage (line 11)
stem(axe,formula);
But when I test the length with length I get the same size. I'll let you be the judge:
-----------------------------------------------------------------------------------
axe,formula = passe_bas(N);
RF = abs(freqz(formula));
f = linspace(0,0.5,length(RF));
end
Unrecognized function or variable 'axe'.
function [axe,formula] = passe_bas(N)
n=-round(N/2):1:round(N/2);
formula=2*v0*sinc(2*v0*n);
-------------------------------------------------------------------------------------
Thanks for your answers.
