摘要：

A possible simplification of digital modulation (carrier multiplication with sine or cosine signal) is discussed. Using the fact that samples of a sine (or cosine) function are periodic under certain circumstances, a novel implementation is proposed. Depending on the ratio of sampling and carrier frequencies this implementation can lead to a reduction of cost in comparison with usual methods of implementation. The paper presents a systematic search for the cases where a certain amount of saving in hardware can be achieved. Copyright © 1979 by The Institute of Electrical and Electronics Engineers, Inc.
