摘要：
An integrated analog to digital and sample rate converter 206 includes sampling circuitry 207 for receiving an analog signal and generating a single or multibit stream of digital signals at a first rate. A leaky integrator filter 208 removes quantization noise from the stream of samples such that resampling can be carried out. Circuitry 209/210 resamples the filtered stream of samples output from leaky integrator filter 208 to generate an output stream of samples at a second rate.
