| titleOfInvention | Method and apparatus for optimally autocorrelating an fsk signal |
| abstract | An autocorrelator for FSK signals. An FSK signal, incoming an a telephone line is filtered by a bandpass filter (13) and sampled by an A/D converter (14). A sample clock (15) provides a fixed sampling frequency, FS. A first interpolating filter (20B) provides selectable delays which are non-integer multiples of 1/FS, and an integer delay (25) provides selectable delays which are integer multiples of 1/FS. The delayed signals are multiplied by a multiplier (26) and then filtered by a low pass filter (27) to provide a filtered autocorrelated signal. A second interpolating filter (20A) provides for reduced jitter in the band timing by increasing the number of samples provided to the decision logic (23). The decision logic (23) provides the decoded data output. |
