摘要
介绍了一种基于PC的语图仪。利用虚拟仪器的思想和短时傅里叶变换的理论,论述了基于PC的语图仪的设 计原理,分析了不同参数选取对处理结果的影响,介绍了该语图仪的编程和实现方法。测试和实际应用证明该语图仪使用 方便,实用性强。
A spectrogram based on PC is presented. By using the idea of Virtual Instrument(VI) and the Short Time Fourier Transform(STFT), design principle of the spectrogram is discussed, the affection between different parameters and programming realization are also analysed. At last, test and application indicate the good function.
