A digital Filter with finite impulse response and thus a limited number of coefficients. The outgoing signal is simply the sum of the products of the incoming signal samples with the filter coefficients.
FIR filters are easy to implement and have many pleasing properties, see also http://en.wikipedia.org/wiki/Finite_impulse_response.
