Program to design bandpass filter with basic mathematical equations, and will be helpful for those who dont have signal processing toolbox.
Trigonometric Sinc function and Hamming window equations are used to create Bandpass filter.
By varying center frequency, Bandwidth parameters, filter can be customized to required frequency.
The same program can be referred to create LPF as well as HPF.
