signal-flow chart

The article brings forward the method of detection noise removing, based on the theory of signal detection and signal detecting on the time frequency chart gotten by time frequency analysis tools.

基于信号的检测理论，在利用时频分析工具得到的时频图上进行信号检测，提出了检测去噪法。

When the measured signal has a very wide frequency chart especially in the fast signal measurement field, in order to easily satisfy the high fidelity requirement that Bandwidth of Long Transmission Line, it is necessary for expanding the Bandwidth of Long Transmission Line.

当被测量信号具有很宽的频谱，尤其是在快脉冲信号测量中，为了测量数据在传输过程中满足高保真度的要求，必须对远距离传输线进行带宽扩展。
