<p>A TRANSFORM MODULATION RECEIVER The receiver receives a transmitted signal of which the modulation is one trigonometric transform function of a desired information signal. The desired signal is recovered by first deriving the Hilbert transform of the sine transform, and multiplying it by the signum of the derivative of the original audio signal to obtain the cosine transform. The sine and cosine transforms are then decoded to obtain the original audio signal.</p> |
