The Butterworth and Chebyshev Type II filters have flat passbands and wide transition bands. The Chebyshev Type I and elliptic filters roll off faster but have passband ripple. The frequency input to the Chebyshev Type II design function sets the beginning of the stopband rather than the end of...
Estimate the modal frequency-response function of the system. Use a Hann window half as long as the measured signals. Specify that the output is the displacement of the mass. Get wind = hann(N/2); [frf,f] = modalfrf(u',y',Fs,wind,Sensor="dis"); The frequency-response function of...
[fn,dr,ms,ofrf] = modalfit(___) also returns a reconstructed frequency-response function array based on the estimated modal parameters. example [___] = modalfit(sys,f,mnum,Name,Value) estimates the modal parameters of the identified model sys. Use estimation commands like ssest (System Id...
The frequency response function describes the amplitude change and phase shift as a function of frequency. To better understand the frequency response function, consider the following description of a linear dynamic system: y(t)=G(q)u(t)+v(t) Here, u(t) and y(t) are the input and ...
