Convolution computations can be simplified by utilizing their inherent properties.

The commutative property reveals that the input and the impulse response of an LTI system can be interchanged without affecting the output.

The associative property suggests that the merged convolution of three functions remains unchanged, irrespective of the sequence in which the convolution is executed.

When two LTI systems with an impulse response are connected in series, their respective equations can be combined using the associative property to derive an equivalent joint impulse, which is similar to the convolution of their individual impulse responses.

The distributive property enables the convolution operation on multiple input signals' sum and simplifies complex impulse responses by breaking them down into simpler components.

The time-shift property implies that delaying the input of a time-invariant system or, if the system has a built-in delay, it results in the output being delayed by the sum of the two delays.

Computationally, this property allows signals to be delayed or advanced to leverage their symmetry or causality, thereby simplifying the convolution operation.
