A method of identification of characteristics of a linear system, at which at its inlet a signal of special shape is fed which is intended for transformation of input original signalinto the incoming changed signal, which sufficiently accurately approximates the required step test signal, according to the formula:,,where,- amplitude and argumentative parts of the operator of Fourier transform respectively,,- amplitude-frequency and phase characteristics of generated linear filter respectively,,- amplitude and phase spectra of the signal of given shape respectively;,- amplitude and phase spectra of the test signal respectively. After this, on the base of known relations the output changed signalis calculated which is used to identify the characteristics of linear system with transient response. |
