DYNAS-dynamic FM filter system

The DYNAS system features an approach which many would consider to be physically impossible: the reception of a broadband transmission spectrum via narrowband filters. This principle seems self-contradictory at first consideration; at any rate, specialists could all easily agree that it does, however, satisfy many of the most critical needs and requirements actually encountered in receiving operations. The following are, of course, the advantages of broadband transmission: high signal-to-noise ratios, high dynamics, and a broad audio-frequency spectrum. The DYNAS principle would couple the above advantages with the following benefits of narrowband transmission: great reception sensitivity, and great immunity to interference. The DYNAS principle would, in addition, eliminate the following disadvantages: relative great susceptibility to interference, and poor signal quality. The above advantages, needs, and requirements are in fact implemented by DYNAS by the technique of dynamic selectivity
