摘要：Filter is one of the most important device to perform the filtering operation for reduction of unwanted components from the actual signal. Bandstop filter is one of the important filter in Signal Processing. In Digital Signal Processing, there are mainly two type of filters, one is Infinite Impulse Response(IIR) Filter and another is the Finite Impulse Response(FIR) Filte. The first one is of recursive type meaning that the present output depends upon the past input, past outputs and the present input but the FIR filter is of nonrecursive type. Domain Transfer Algorithm (DTA) is applied to the predesigned analog filter to design its equivalent digital filter with less erro r and with increased computational speed. The Magnitude response shows the accuracy and the Pole-Zero plot shows the stability of the filter.
