ABSTRACT:
A method and apparatus for providing a selected amount of power from a power source to a load produce a pseudo random code sequence of different type bits, in which one type of the different type bits is used to control application of power from the source to the load so that the power applied to the load corresponds to the total of the number of the bits of one type applied to the load in a given time period. A plurality of code sequences is provided, with each corresponding to a different power level, and a sequence can be selected to provide a selected power level to the load.
