What is the output of LTI system?
This function exists in the time domain of the system. For an arbitrary input, the output of an LTI system is the convolution of the input signal with the system's impulse response. In addition to linear and time-invariant, LTI systems are also memory systems, invertible, casual, real, and stable.
What is the condition for a discrete time LTI system to be causal?
A discrete-time system is causal if: Whenever the input x[n] = 0, and there are no initial conditions, the output is y[n] = 0. The output y[n] does not depend on future inputs.
What is LTI discrete time system?
“Discrete–time, linear, time invariant systems” refer to linear, time invariant circuits or processors that take one discrete–time input signal and produce one discrete–time output signal.
Which of the following is condition of causality for an DT LTI discrete time system?
Which of the following system is causal? Explanation: An LTI system is said to be causal only when its output at any time depends on the previous or present value of the input. A causal system cannot depend on the future values of the input.
