Hello,
I have a problem with the use of the functions fir1() and fir2() in Matlab.
The bandpass example on the fir() page here https://de.mathworks.com/help/signal/ref/fir1.html#bulla9m shows, how to design a bandpass dependent on the normalized frequencys. So as far as I understood, the normalized frequenzy is
. But what I can't find is, what sampling frequency
has been used? For my filter design, I want to use a specific
. How can I set this as a parameter for the functions, or what am I not understanding here? In the filter designer app, it is also possible to specify the sampling frequency. But there, I have problems exporting the filter coefficiants to a vector in matlab
