Make a page about interpolating FIR filters. Take care to note how many multiply/add operations.

An interpolting filter is when you create "in-between" samples from the original sample resulting as if you had sampled the signal at a higher rate. Interpolation only works with integers.

The are under the rth impulse function of the interpolated signal is

$y(t)=\sum _{r=-\infty }^{\infty }y(r)\delta (t-\left({\frac {\left(rt\right)}{2}}\right))$

For every T seconds, the number of add/multiply operations is

$(2M+1)(1/2)\!$
