Digital RF receiver

DETAILED DESCRIPTION It is a principle object of the present invention to provide a digitally enhanced RF receiving system for receiving and processing useful information from a relatively weak RF signal.
Another object of the present invention is to provide a discriminator circuit for digitally processing a RF signal in a noisy environment.
And yet another object of the present invention is to provide a relatively fast digital processor having applications in the long range RF telemetry field.
And still another object of the present invention is to provide a system and method for maximizing the benefits of DSP technology combined with conventional receiver circuitry for processing received analog signals.
Yet another object of the present invention is to provide a system and apparatus having precise tone decoding or detection capability of relatively weak signals in a noisy environment.
And still a further object of the present invention is to provide a RF receiving system having applications in the personal paging market, particularly an acknowledgement paging system.
Yet another object of this invention is to provide a RF data transfer system capable of processing useful information from relatively weak analog signals.
A still further object of the present invention is to provide a digital receiver for receiving and demodulating weak signals in the presence of narrow band and wide band interference effectively increasing the signal to noise ratio magnitudes greater than known conventional techniques.
Still another object of this invention is to provide a dynamically recursive digital discriminator for the demodulation of FM (frequency modulation) radio signals.
And yet another object of the present invention is to provide a dynamically recursive digital discriminator circuit for the demodulation of bicromatic monotonic AM radio signals.
Another object of this invention is to provide a personal acknowledgement paging system incorporating a relatively small and weak acknowledgement transmitter with a portable receiver whereby a digitally enhanced receiving system can process the acknowledgement signal from the personal transmitter in a relatively noisy environment
