Abstract :

In some European countries, the electric power stations sends out controlling codes modulated onto the net frequency in order to
synchronize all the public timers. These features are detected as modulated noise by the light controllers in the house. A digital
filtering technique that does not require a dedicated digital signal processor is presented. A small, low-cost, 8-b processor
is used to handle the remote-control commands and at the same time digitally process the signals fed to the triac-component in
order to remove blinking effects and direct-current displacements. The noise cancelling method is described, and
general results and some suggestions for improvements of the method are given.
