Abstract
A system and method for converting a first digital input signal having a first sample size per unit length and a first bandwidth to a digital output signal having a second sample size per unit length. The input signal is passed through a first filter means which decimates the signal to a smaller sample size and outputs a decimated signal. A second filter limits that bandwidth of the decimated signal and outputs a bandlimited signal. Next, a third filter interpolates the bandlimited signal to produce a digital output signal having the desired sample size.
