摘要
Abstract
Various design methods of FIR filter are summarized and their characteristics are analyzed.Then,a reconfigurablc FIR filter system is presented.According to the filter specialties,the filter coefficients are calculated by PC computer.And the configured coefficients of the multistage FIR filter are downloaded to the chip.The filter computing is completed by the FPGA.The filter data are transmitted to the computer through the USB2.0 interface for further processing,such as displaying,analyzing and storing.The state conversion between the coefficient configuring mode and the filter mode is finished by finite state machine,thus ensuring the system to work orderly.The verifying experiments and the application examples show that the coefficient configuring of the system is easy and the filter result is effective.关键词
