by means of a recursive algorithm using one or more sets of parameters stored in a memory and the calculated amplitudes of one or more preceding sample points

Full Title

Instruments in which the tones are synthesised from a data store, e.g. computer organs > by calculating functions or polynomial approximations to evaluate amplitudes at successive sample points of a tone waveform > by means of a recursive algorithm using one or more sets of parameters stored in a memory and the calculated amplitudes of one or more preceding sample points
