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