Where can I find response of LTI system?
A linear time-invariant (LTI) system can be represented by its impulse response (Figure 10.6). More specifically, if X(t) is the input signal to the system, the output, Y(t), can be written as Y(t)=∫∞−∞h(α)X(t−α)dα=∫∞−∞X(α)h(t−α)dα.
How do you find the frequency response of a LTI system?
−jΩm = C(Ω) − jS(Ω) = H(Ω) . , where H(Ω) is the frequency response of the LTI system. The system therefore produces an output signal that is the “3-point weighted moving average” of the input.
How do you determine if an LTI system is stable?
Time Domain Condition for the Stability of LTI Discrete-Time Systems. For a system, when the bounded input sequence always produces a bounded output sequence, then the system is said to be stable system.
What is meant by step response of an LTI system?
The step response of a discrete – LTI system is the convolution of the unit step with the impulse response i.e. s(n) = u(n) * h(n) s(n) = Step Response. It is the response of the LTI system to a step input u(n).
