hey guys .(adsbygoogle = window.adsbygoogle || []).push({});

i have this discrete signal : z/(z-(e^-2T))

and i want to get a frequency response of it...

i use the matlabe function : freqz

but the problem is that it only plots up to the angular frequency of 1!!! i.e. its a normalized frequency...

does anybody know how i can make it plot up to w =100 for example?

i need to do this so i can compare it to my continuous signal and analyze any alising that may occur..

thanks

John
