Abstract:
A method for generating an output signal according to specified criteria using a control signal and a bias signal, the control signal having a control frequency, and the bias signal having a bias amplitude, comprising the steps of:(1) selecting output signal criteria relating to at least one of a desired frequency, a desired period, and a desired amplitude for the output signal; (2) establishing said desired amplitude for the output signal, wherein step (2) comprises at least one of steps (a) and (b): (a) shaping the control signal according to said output signal criteria to create a shaped control signal, said shaped control signal comprising a plurality of pulses; and (b) controlling a gain of the output signal by adjusting the bias signal; and (3) gating the bias signal at a rate corresponding to the control frequency or a frequency of said shaped control signal to create a periodic signal, said periodic signal having a periodic signal amplitude, a periodic signal frequency, and a periodic signal pulse width, and wherein said periodic signal frequency corresponds to the control frequency or said frequency of said shaped control signal, said periodic signal being comprised of a plurality of harmonics, wherein at least one of said plurality of harmonics is a desired harmonic; â€ƒwherein step (2)(a) comprises at least one of steps (i) and (ii): (i) frequency regulating said shaped control signal such that said frequency of said shaped control signal corresponds to a subharmonic frequency of said desired frequency; and (ii) pulse regulating said shaped control signal to control a pulse width of each pulse of said plurality of pulses of said shaped control signal, said pulse width being a shaped signal pulse width.
