Performance Analysis on Frequency Response of Finite Impulse Response Filter

Digital finite impulse response (FIR) filters are very useful to digital devices such as hand phones, digital cameras and tablet computers and in many more digital product. The important behind this is digital signal processor and all these products working as the brain of human if we compared to advance signal processing (ASP). One of the common and suitable processing technique is filtering. Here we focus on three window technique named as parks McClellan, Rectangular and Kaiser window technique as well as some prototype filter deign and showing some result with respect to their filter characteristics.
