Explain about Infinite Impulse Response.

- IIR is one of the properties of signal processing systems.

- An impulse response function that is none-zero over an infinite length of time is available in IIR systems.

- An analog filter by name RC filter is made up of a single resistor for feeding into a node.

- This is shared with a single capacitor.

- An exponential impulse response is available in this filter that is characterized by an RC time constant.
