| Title of Invention | APPARATUS FOR COMBINED MULTIPLE FREQUENCY SIGNALS. |
|---|---|
| Abstract | The present invention is in the field of filters for electromagnetic signals and relates to the technical problem of separating the components of multiple frequency signals and accurately extracting transmitted data. There is disclosed a method and apparatus for reducing the distortion imposed upon a combined information wave (72) by a receiver filter or other signal processor. The said method involves a step of adjusting the amplitudes of the positive (75) and negative (74) segments of the combined information wave (72) such that the positive (75) and negative (74) segments have preselected and equal amplitudes thereby producing an amplitude adjusted combined information wave (76). The apparatus has an adder circuit for combining the component information waves (70) and the reference wave to form the combined information wave (72), a wave shaper to produce an equalized wave, and a wave multiplier for proportionally adjusting, on a half cycle basis, the amplitudes of the equalized positive and negative segments. The principal use of the invention is in communications and data transfer. |
