ABSTRACT:
A signal receiving apparatus and method are provided to decode an input signal to determine the presence of at least one desired frequency component in that input signal. A number of signal samples are taken in relation to the known frequency of that signal component, and data compaction and analysis operations are performed to identify that desired frequency component. A multiple comparison made with a predetermined threshold magnitude is provided to identify the frequency component in that input signal.
