Abstract


Signal processing, communications, and computers all rely heavily on the field of digital signal processing (DSP). In DSP important application is Finite impulse response (FIR) filter. The initial objective of this inquiry is to present an approach for an improved framework of a FIR digital filter through the programme level to the hardware level. It influences the decision on design approaches, architecture, and the efficient use of hardware. The window design method appears to be reasonably straightforward and user-friendly due to the availability of a clearly stated equation, according to theoretical and experimental results on the FIR bandpass filter. This study compares various window types and finds that the Kaiser Window provides the smallest main-lobe width with an abrupt cut-off and the smallest amount of transition band. The results of this study demonstrate the simplicity of the Direct-Form structure technique, which outperforms all other common filter structures. As a result, the design is more resilient, smaller, and less expensive, all of which effectively lower quantization mistakes. This study examines the impact of quantization on frequency response for the effective realisation of hardware by gradually reducing the number of bits in each coefficient using an iterative approach until its frequency response satisfies the innovative requirements. An investigation of coefficient quantization defines the relationship between the quantity of bits, the quantity of coefficients, and the frequency response, which results in a smaller footprint and faster processing. Computer-Aided Design (CAD) tools are utilised for carrying out the design utilising the behavioral-level method.
