On window parameter selection of short-time Fourier transform with Gaussian window in detection of LFM signals; 基於短時(shí)傅裡葉變換形成的三維譜圖，採(cǎi)用數(shù)字圖像処理的方法提取信號(hào)的特征。
This paper studies the window parameter selection of short-time Fourier transform(STFT) with Gaussian window in detection of linear FM signals. 研究了高斯窗短時(shí)傅裡葉變換對(duì)線性調(diào)頻信號(hào)檢測(cè)的窗口蓡數(shù)的選擇。
The real arbitrary waveform generator that can generate single acoustic frequency signal modulated by Manning window and Gaussian window is developed. 成功地實(shí)現(xiàn)了漢甯窗、高斯窗調(diào)制的任意頻率單音頻信號(hào)的産生，達(dá)到了任意波形發(fā)生器的功能。
