The discrete transfer function of a FIR filter
After seeing its behavior over time, we derive the transfer function of an FIR filter and the conditions for it to introduce a linear phase shift with frequency. […]

FIR digital filters
The output of an FIR filter at a certain moment is given by the linear combination of the input samples taken in a finite number of previous moments. […]
