Most discrete-time signals encountered in practice can be represented as a linear combination of a very large, maybe infinite, number of sinusoidal discrete-time signals of different angular frequencies ? Thus, knowing the response of the LTI system to a single sinusoidal signal, we can determine...
This brings about perfection and unity of response solution of LTI continuous-time systems on time-domain. The result shows that total response and zero-input response of LTI Continuous-Time Systems relate not only to system's initial status r ( k)(0_) but also to excitation signal value e...
