| Abstract: | When an ideal STRETCH signal passes through a linear system and then the output signal is mixed with an ideal STRETCH signal, one can get an intermediate-frequency (IF) signal which includes the amplitude and phase characteristics of the linear system. The analysis results given in the paper indicate that the amplitude-frequency characteristic of the IF signal is modulated by that of the linear system, and the phase-frequency characteristic of the IF signal is modulated by that of the linear system. |
