| Abstract: | Based on the digital switching system, this paper presents the method of
designing digital sound-signals and digital multifrequency signals. The principle of
circuits, method of encoding, design of level and the relation of pulse signals are
discussed. Finally the principle of circuits is demonstrated and result of experiment
is given. |
