Implementation of Low, High and Band Pass Filters using Verilog HDL

Abstract

Filters are some of the highly essential components used for operating in most electronic based circuits. Filters are most important and widely used to block some portion of signals according to frequency. Having a detailed knowledge of various filters. A designer will be able to design an efficient communication networks, by varying the cut off frequencies. Filters are required in computer, mechanical and some other fields too. As days passed by the usage of active and passive filters has gradually increased in the market. There are various types of Filters available, in which we are going to perform the simulation of Low pass, High Pass and Band pass Filter using Verilog Hardware Descriptive Language and Xilinx ISE 13.1 as a simulation tool. This paper provides a detailed explanation, circuit diagram, advantages, disadvantages, applications, working of Verilog code and simulation result of Low pass, High pass and Band pass filter. Using Verilog Hardware Descriptive language its simpler to understand and execute the functionality of filters then using other tools like MATLAB, Microcontroller, Microprocessor.
