Webcircle. Combining these two properties, a causal LTI system with a rational system function H(z)is stable if and only if all of the poles of H(z)lie inside the unit circle.i.e., the magnitude of poles must be less than 1. Thus, stability of a IIR system can be determined by looking at the pole location. Web22 May 2024 · When a system is "shocked" by a delta function, it produces an output known as its impulse response. For an LTI system, the impulse response completely determines the output of the system given any arbitrary input. The output can be found using discrete time convolution.
