Hello, I am new to matlab. I want to design FIR,Butterworth and some RC filters in Matlab with GUIDE. Someone told me that I can design it using Signal Processing Toolbox. Is it possible to implement these filters without any toolboxes otherthan just matlab and GUIDE.
Yes, it is possible, but you will have to write a lot of code. The Signal Processing Toolbox (SPT) enables you to create these filters easily. Filter design code can be very complicated, so you will have to invest a lot of time to do it without SPT.
