Fecha de publicación: 15/04/1997 Fuente: Wipo "digitalization" A digital-to-digital sample rate converter for converting digital input signals x(n) having a first sample rate F into digital output signals y(m) having a second sample rate F.multidot.L/M, wherein L/M is an arbitrary rational fraction. The digital lowpass filter needed for sample rate conversion has a piecewise continuous linear hull curve. This allows an efficient and low-cost hardware solution, since only one multiplier is needed for the digital-to-digital sample rate converter.
