Design and Realization of FIR Band-pass Digital Filter Based on MATLAB

摘要：

　　Digital filter is one of the most important parts of digital signal processing.In practice,digital signal processing often need to limit the signal observation time interval within a certain time,choose only one period of signal that signal data will be truncated,this process is equivalent to plus window function operation to signal.In order to obtain finite unit sample response,need to truncate the infinite unit sample response sequence by window function.This paper proposes the method of using window function to design FIR Band-pass filter based on MATLAB,according to the design basic principle of FIR digital filter.Filtering processing for measured signal showed that filtering effect of the filter achieved the expected results.
