btlbandstop
- 巴特沃特带阻滤波器的设计，返回分子分母多项式系数，还可以作出增益曲线，以及求出相位响应以及群延时响应-Batewote band stop filter design, the return of molecular denominator polynomial coefficients, can gain curve, and the calculated phase response and group delay response
pudn2
- 一般来说，瞬时频率和群延迟在时频平面内定义了两条不同的曲线，但是在时宽（T）和频宽（B）的乘积值逐渐变大时，这两条曲线会慢慢逼近。为了说明这一点，下面计算了信号的瞬时频率和群延迟，T*B值大。-Generally speaking, the instantaneous frequency and group delay in the time-frequency plane defines two different curves, but when the width [T] and band
