Abstract
Digital filters are typically used to modify or alter the attributes of a signal in the time or frequency domain. The most common digital filter is the linear time-invariant (LTI) filter. An LTI interacts with its input signal through a process called linear convolution, denoted by y = f * x where f is the filter’s impulse response, x is the input signal, and y is the convolved output. The linear convolution process is formally defined by:
