A circuit that changes the word rate of pulse code modulated signals
In this paper we describe a circuit that accepts pulse code modulated signals sampled at about 8 kHz and resamples them at any desired rate up to 512 kHz. When the sampling satisfies Nyquist's criterion, the distortion introduced is at least 35 dB below the signal level. The circuit uses a digital low-pass filter to interpolate sample values, and it may be integrated as about 2500 gates on a 5 mm2 chip.
