Open Live Script. Fit a 4th-order IIR model to the impulse response of a lowpass filter. Plot the original and Prony-designed impulse responses. WebProny's Method. Prony's method is a technique for extracting the sinusoid or exponential signals by solving a set of linear equations for the coefficients of the recurrence equation that the signals satisfy. It is closely related to Pisarenko's method, which finds the smallest eigenvalue of an estimated covariance matrix.
WebProny's method is an algorithm for finding an IIR filter with a prescribed time domain impulse response. It has applications in filter design, exponential signal modeling, and system identification (parametric modeling). [b,a] = prony (h,n,m) finds a filter with numerator order n, denominator order m, and the time domain impulse response in h.
