i have an exercise to design analog low pass filter chebyshev type 2 with this specifications Ωp=o.4 pi Rp=2dB Ωs=0.5pi As=20dB
I have to do matlab code to show impulse response and amplitude response but i dont know how to do it.. i dont have Fs either :S.. please help me.. i have to do it till tomorrow..
Its pretty simple to design digital filters in matlab as opposed to languages such as C or C++ or Java. this is because matlab has its own toolboxs to design filters. you can look for a toolbox called "fdatool". Just type fdatool in the matlab command prompt, and the toolbox opens up. there is a significant amount of help in the matlab help documents on this issue too.
Its pretty simple.
