Design of Low pass FIR Filters using Kaiser Window Function with variable parameter Beta (β)

Abstract

The paper deals with designing of low pass Finite Impulse Response filter using Kaiser Window with variable parameter beta (β) between 0 and 4, further a comparative study is made at different filter orders so as to control the transition bandwidth.  The Kaiser window is chosen as it contains an adjustable parameter with which main lobe width and correspondingly minimum stop band attenuation of   designed filter can be controlled.
