impulse invariance

脉冲响应不变法

脉冲响应不变法(Impulse Invariance) 1.变换原理数字滤波器的单位脉冲响应序列h(n)正好等于模拟滤波器的冲激响应ha(t)的采样值，即h(n)=ha(nT),T 为采样周期。

abstract: Impulse invariance is a technique for designing discrete-time infinite-impulse-response (IIR) filters from continuous-time filters in which the impulse response of the continuous-time system is sampled to produce the impulse response of the discrete-time system. The frequency response of the discrete-time system will be a sum of shifted copies of the frequency response of the continuous-time system; if the continuous-time system is approximately band-limited to a frequency less than the Nyquist frequency of the sampling, then the frequency response of the discrete-time system will be approximately equal to it for frequencies below the Nyquist frequency.
