Self adjusting data detector

DETAILED DESCRIPTION Accordingly, it is an object of the present invention to provide an improved data detector which recovers a transmitted digital signal having the original timing of the transmitted digital signal.
It is a further object of the present invention to provide a data detector which is free from data dependent jitter.
It is still a further object of the present invention to provide a data detector capable of compensating for changing modulation levels.
It is yet another object of the present invention to provide a data detector having a data slicer circuit directly coupled to the receiver circuit.
In carrying out the above and other objects of the present invention in one form, there is provided a circuit comprising an R.
F.
amplifier coupled for receiving a modulated carrier signal, an I.
F.
amplifier coupled to the R.
F.
amplifier, and a detector circuit coupled to the I.
F.
amplifier for removing the carrier signal from the modulating data signal and amplifying the data signal.
A first feedback circuit is coupled to the detector circuit, and to the R.
F.
amplifier and to the I.
F.
amplifier for limiting the peak magnitude of the data signal.
A second feedback circuit is coupled to the first feedback circuit and to the detector circuit for setting and maintaining a desired operating point of the detector circuit.
The above and other objects, features, and advantages of the present invention will be better understood from the following detailed description taken in conjunction with the accompanying drawings.
