A key point in Short Time Fourier Transform is the choice of window function. Although rectangle window is regarded as the first choice because it's featured by integral harmonic to filter signals and by DC component, decaying DC component and frequency shift of signals cause great error to rectangle window STFT. In addition, transient signals contain rich information of faults, but the fixed time window of STFT fail to collect these information.
STFT 算法关键问题之一是窗函数的选择,矩形窗以滤除信号整数次谐波和直流分量的特点自然称为首选窗,但衰减直流分量和信号的频率偏移对矩形窗 STFT 造成了很大误差;其次,暂态信号中含有丰富的故障信息,傅立叶变换固定的频窗忽略了这些特征信息。

In order to measure the passive network's conduction automatically, a network conduction instrumentation based on FPGA technology was designed and implemented according to the design principle of Virtual Instrument. System adopted FPGA technology building a digital flat-top to imitatively produce the high quality sine signal. Under the control of C8051MCU, measurement, calculation and display of the port network's conduction were automatic implementation. Furthermore, the system has the function of frequency step measurement.
