本程序用Blackman窗技术设计有限冲激响应数字滤波器。包括低通、高通、带通和带阻滤波器。数字滤波器的采样宽度可取到1024点。为设计窗数字滤波器要求给出滤波器的归一化截止频率和窗参数。为便于比较,程序中还配备了HANNING窗、HAMMING窗和KAISER窗。程序采用模块结构。输入数据和程序控制信息以人机通讯方式由控制台输入。设计结果由行打印机和显示屏幕同时输出。本程序在CROMEMCO微型计算机上调试通过。
This program uses Blackman window technology to design a finite impulse response digital filter. Including low-pass, high-pass, band-pass and band-stop filter. Digital filter sampling width can be taken to 1024 points. The design of the window digital filter requires the normalized cutoff frequency and window parameters of the filter. For ease of comparison, the program is also equipped with HANNING window, HAMMING window and KAISER window. Program using modular structure. Input data and program control information are input by the console by means of human-machine communication. The result of the design is output simultaneously by the line printer and the display screen. This program is debugged on the CROMEMCO microcomputer.
