How do you explain impulse response?

An impulse response (or IR) is a sonic measurement of the sound of a speaker, room or microphone in relation to a sound source. In guitar terms, this is usually your amp. After your guitar itself and the dialled-in tone of your amp, there's a lot more that can affect your sound.

How do you solve impulse response?

Given the system equation, you can find the impulse response just by feeding x[n] = δ[n] into the system. If the system is linear and time-invariant (terms we'll define later), then you can use the impulse response to find the output for any input, using a method called convolution that we'll learn in two weeks.

What does impulse response function tell us?

An impulse-response function describes the evolution of the variable of interest along a. specified time horizon after a shock in a given moment.
