ABSTRACT:
An apparatus and method for processing a signal is capable of determining the presence of absence of a signal having a predetermined baud rate. By initializing counting registers to either first or second values, and receiving the signal, either the presence or absence of the baud rate may be more rapidly detected. Rapid detection provides for improved battery savings when the invention is used within a portable receiver such as a pager. The invention provides for positive detection of the predetermined baud rate while rejecting a baud rate being an integer divisor of the predetermined baud rate. Additionally, as a result of the determination of the presence of the predetermined baud rate, a sample clock may be established for receiving data at the baud rate.
