ABSTRACT:
An apparatus for receiving and processing digital signals. Techniques and apparatus are disclosed for reducing power consumption in digital receiving and processing circuits without manual intervention and without data rate reduction. The digital signal comprises a leading, slower data rate signal and a trailing, faster data rate signal. When the pre-defined leading signal is received, a slower digital-signal processor processes that signal and then activates a faster digital-signal processor which processes the trailing, faster signal. After processing the trailing signal, the faster digital-signal processor is deactivated.
