The time frequency window is adjusted conveniently by using optimum base searching method, moreover, it's not necessary to have stable wave assumption in the window.
通过采用局部余弦最佳基搜索方法，对信息实现不同的时间分割，可非常容易地调整时频窗。 不需要在分析窗内对信号作平稳假定，所得结果与原信号完全同步。
This algorithm needs shorter data window time and has higher calculation precision and is not affected by deviation of power frequency.
这种算法具有所需数据窗的时间短、计算精度高和不受系统频率偏差影响的优点。
There will be an antinomy among sample frequency, memory capacitance and the width of window of sample time for developing the resolving power of LA while we taking the LA to test an digital system.
在用逻辑分析仪测试数字系统时，为了提高逻辑分析仪的分辨力，会产生采样频率、存储容量与采样时间窗口宽度之间的矛盾。
