of the Invention, ELECTRONIC SYSTEMS AND EFFECTIVE REDUCTION OF ELECTROMAGNETIC INTERFERENCE ENERGY PROPAGATION FROM ELECTRONIC SYSTEMS An electronic system includes at least one element which is operative in response to clock signal pulses of, less than a maximum frequency of occurrence from a clock, signal source. A dither means is connected to the clock signal source for causing the frequency of occurrence to be varied such that electromagnetic radiation which accompanies the normal operation of the system is of a lesser interference effect than if the frequency of occurrence were substantially monotonous.

Why it's free to use
- Filed May 30, 1990 and granted May 11, 1993. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 30, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 30, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
