2. Finite impulse response filters

The output value at time n ( y(n) ) is calculated from a finite number of previous input samples: y(n)=∑k=0Hakx(n−k)

As the number of terms is finite, so is their sum: a transversal filter is therefore always stable. This quality is essential and allows us to build very complex filters, such as the adaptive filters we'll briefly...
