ASIC Design of Sample Rate Convertor

At present, video and audio are mostly based on complete digital processing of a signal. Therefore more problems come if the equipment is based on different sampling rate. Before it was only signal digital processor and in particular signal chain and we had Analog to Digital or Digital to Analog converters used in those chains. Since the era now uses almost all digital we need a digital interfacing between different digital equipment and it-s called as Sample Rate Converter. Therefore sample rate converter is a device used for converting a signal frequency from one to another.
