用于Prony分析的数据

Prony Toolbox demos are provided in the demos directory. Pure Signal Demo The pure_demo MAT-file contains a demo of a pure signal. The signal Y is constructed using 3 real damped sinusoids or 6 complex damped sinusoids: c1 = 2e (-50t)sin(2π100t+π). c2 = 3e(-20t)sin(2π200t+π/2). c3 = 4e(-100t)sin(2π400t). Y = c1+c2+c3. Signal with Pure Tone Noise Demo The puretone_demo MAT-file contains a demo of a signal with a pure tone noise. Test signal “Y1” is a noisy signal with pure tone noises n1 and n2. c1 = 2e (-50t)sin(2π100t+π). c2 = 3e(-20t)sin(2π200t+π/2). c3 = 4e(-100t)sin(2π400t). n1 = sin(2π150t). n2= 6sin(2π300t). Y1 = c1+c2+c3+n1+n2. Signal with Broadband Noise Demo The bbnoise_demo MAT-file contains a demo of a signal with a broadband noise. The testsignal Y2 is constructed Test using the following components: c1 = 2e (-50t)sin(2π100t+π). c2 = 3e(-20t)sin(2π200t+π/2). c3 = 4e(-100t)sin(2π400t). n = 2 randn(1,200). Y2 = c1+c2+c3+n.
