Abstract
The invention describes methods and systems for digital synthesis of electric signals. According to the invention, one or more bit-patterns are provided, each indicative of a rectangular waveform having a characteristic frequency. Further to determining a selected signal frequency to be synthesized, a selected bit-pattern associated therewith is obtained. Bits of the selected bit-pattern are cyclically serialized to generate a substantially rectangular waveform signal comprising the characteristic frequency. Then, the signal is filtered to suppress spurious frequencies outside a certain unfiltered frequency band which corresponds to the selected bit-pattern to thereby obtain a filtered signal with prominent frequency component corresponding to the selected signal frequency.
