The steady-state response is the output of the system in the limit of infinite time, and the transient response is the difference between the response and the steady state response (It corresponds to the homogeneous solution of the above differential equation.) The transfer function for an LTI system may be written as the product:... Difference Equations A general linear constant-coefficient difference equation for an LTI system with input x[n] and output y[n] is of the form Now applying the FT to both sides of the above equation, we have But we know that the input and the output are related to each other through the impulse response of the system, denoted by h[n], i.e., 45 Properties of the DT FT : Difference equation

The corresponding frequency response (characteristic). The input/output mathematical model is also called the external description of the system. In the following we will show that the N-th order input/output differential equation can be used to obtain N equations in N internal variables and the input and an output equation relating the output to the N internal variables and the input. These

Impulse Response The impulse response of a linear system h ˝(t) is the output of the system at time t to an impulse at time ˝. This can be written as h ˝= H( ˝) Care is required in interpreting this expression! H 0 t
- 1 Frequency response of LTI systems The phase distortion of the ideal delay is therefore a linear function of !. This is considered to be a rather mild (and therefore acceptable) form of phase distortion, since the only effect is to shift the sequence in time. In other words, a ﬁlter with linear phase response can be viewed as a cascade o f a zero-phase ﬁlter, followed by a time shift
