Abstract
A signal generator, system, and method for electromagnetically heating of a hydrocarbon formation. The method involves determining a desired output signal having a desired power spectral density; generating a plurality of source signals, based on the desired output signal; modulating the plurality of source signals, based on the desired output signal, to provide a plurality of modulated signals capable of providing the desired power spectral density; combining one or more of the plurality of modulated signals into a combined signal; transforming the combined signal to have the desired power spectral density, thereby providing at least one output signal; and applying the at least one output signal to a load having a frequency-dependent impedance to produce at least one standing electromagnetic wave along a length of the load. The at least one standing electromagnetic wave includes at least a partial standing electromagnetic wave.
