ABSTRACT:
A sample rate converting device includes a noise shaper and a sample rate converter. The noise shaper is for receiving a digital input signal, noise-shaping the digital input signal, and then outputting an n-bit digital stream. The sample rate converter, which is coupled to the noise shaper, receives the n-bit digital stream and outputs a digital output signal. Since the n-bit digital stream is a digital signal with a smaller number of bits in each sample, the computation efforts of interpolation are reduced. Hence, less resource is needed to complete the conversion.
