Abstract
A data receiver, which could be an optical transceiver, a modem, a router hub, is capable of detecting the transmission rate of incoming data. The data is converted to electrical waves appropriate for passive or active bandpass filtering. The frequencies at which the waves are filtered are determined from a plurality of known possible transmission rates and are chosen as having the most detectable difference in the power spectra. By implementing a filter at the corresponding frequency(ies), data having that (those) frequency(ies) will be transmitted. A signal detector then can receive a signal transmitted through the filter and determine the corresponding data rate. It is further contemplated that the multiple frequencies can be filtered by using stages of filters and signal detectors for different frequencies or by filters and detectors capable of multiple frequency operation.
