The invention is a method and apparatus for (1) enhancing the transmission of information in a particular direction or (2) enhancing the reception of information from a particular direction by an array of transducers, a transducer being any device for transforming radiated power into electrical power and vice versa. A transducer signal is associated with each transducer in an array, the plurality of transducer signals being the vehicle for transmitting or receiving information. Each transducer signal is the sum of a first product and a second product. The first product is the product of a first signal and a cosine function of an argument. The second product is the product of a second signal and a sine function of the same argument. An argument is the sum of a phase and a product of an angular frequency and time. The bandwidths of the first and second signals are less than half a reference frequency W, and the angular frequency of the sine and cosine functions is greater than 2π times the reference frequency. The method comprises the steps of (1) adjusting the arguments of the sine and cosine functions and (2) adjusting an embedded time reference in the first and second signals with respect to a real-time reference.
