ABSTRACT
The paper is based upon the performance of various windows in designing FIR Filter. The cosine hyperbolic window has been used to design a better FIR Filter in terms of ripple ratio, side-lobe roll off ratio and main-lobe width with its advantages of no power series expansion in frequency domain hence need less hardware. The spectral characteristic of cosh window is compared with other windows like Kaiser Window, hamming window and their combinations. A modification is also introduced in cosh window to perform better in terms of ripple ratio as compared to Kaiser as well as cosh window.
