Abstract: Apparatus and methods are disclosed for transmitting very fast digital DC signals over the track for remote control in a model railroad layout, by selecting positive and negative lobes from the applied AC track power signal. This method allows digital transmission at 120 Hz rate that can be used within a 60 Hz AC system. This is fast enough to be used for Digital Command Control (DCC) and also capable of delivering large power output efficiently without the expense of filtering or exotic electronic control circuits. This method also has low sensitivity to electrical noise and does not generate significant noise during operation. We describe methods of transmitting and receiving positive and negative lobes and methods to extend this technology. We also describe other areas where this technology can be applied such as remote control of appliances connected to any AC power environment such as home or industrial electric power systems.
