本设计采用TMS320F28234 DSP芯片，设计了一台音频频率数字扫频仪。系统由扫频信号产生及调理模块、帯阻网络模块、幅频特性测试模块、数字幅频均衡模块以及人机交互模块组成。扫频信号由DSP内部PWM模块产生经外部有源低通滤波器进入带阻网络。应用数字信号处理技术在 DSP内部实现幅频特性测试，测试结果通过DSP的SCI在电脑显示器上显示，幅频均衡部分利用利用Matlab和基本部分中测得的陷波特性得出均衡算法中的滤波器的系数和阶数，然后在DSP内部对帯阻网络实现了均衡，完成了要求的各项指标。-A digital audio frequency sweep generator is developed with TMS320F28234 DSP chip in our design. The system consists of a sweep signal generation and conditioning module, band-stop network module, amplitude-frequency characteristic test module, digital amplitude-frequency equalization module and interaction module. The sweep signal generated by PWM module inner DSP pass the low-pass filter and then input the band-stop network. Digital signal processing technology is used in DSP to test the amplitude-frequency characteristic, and the test results are showed on computer monitor by the SCI of DSP, the amplitude-frequency equalization section computes the coefficients and order of the filter by matlab and trap characteristic measured in the basic part, then we achieve the equalization of the band-stop network, and complete all the requested indicators.
