Design and simulation of FIR filter based on GUI

A novel method to simulate the FIR filter based on GUI(Graphic User Interface) is introduced in this paper. This method not only depended on Matlab code, but also made use of controls which generate a GUI. All the operations have been done by GUI. This paper took window-function method to realize FIR filter for example to design digital low-pass, high-pass and band-pass filters. The simulation results demonstrate that the design based on GUI is convenient, fast, intuitive and flexible. In the meantime, it offered a clue and method for the design of digital filter.
