Abstract
Systems and methods synthesize a signal from the odd harmonic frequency components of an input signal. An exemplary embodiment synthesizes a first signal with a digital to analog converter (DAC), generates a second signal from the first signal, and filters a selected one of the odd harmonic frequency components through a band pass filter to produce an output signal. The first signal is defined by a first frequency. The second signal is defined by the first frequency and comprises a fundamental frequency component and plurality of odd harmonic frequency components. The output signal has a frequency substantially equal to the frequency of the selected odd harmonic frequency component.

A method for synthesizing a signal, comprising:
- synthesizing a first signal with a digital to analog converter (DAC), the first signal defined by a first frequency;
- generating a second signal from the first signal, the second signal defined by the first frequency and comprising a fundamental frequency component and plurality of odd harmonic frequency components;
- and
- filtering a selected one of the odd harmonic frequency components through a band pass filter to produce an output signal, wherein the output signal has a frequency substantially equal to the frequency of the selected odd harmonic frequency component.
A signal synthesizing system, comprising:
- a digital to analog converter (DAC) operable to generate a first signal, the first signal defined by a first frequency;
- a comparator communicatively coupled to the DAC, operable to receive the first signal from the DAC, and operable to generate a substantially square-shaped waveform signal in response to receiving the first signal, wherein the substantially square-shaped waveform signal comprises a fundamental frequency component and plurality of odd harmonic frequency components;
- and
- a band pass filter communicatively coupled to the comparator, operable to receive the substantially square-shaped waveform signal from the comparator, and operable to filter the substantially square-shaped waveform signal to produce an output signal corresponding to a selected one of the odd harmonic frequency components of the substantially square-shaped waveform signal received from the comparator, wherein the band pass filter output signal has a frequency substantially equal to the frequency of the selected odd harmonic frequency component.
A system for synthesizing a signal, comprising:
- means for synthesizing a first signal defined by a first frequency;
- means for generating a second signal from the synthesized first signal, the second signal defined by the first frequency, and comprising a fundamental frequency component and plurality of odd harmonic frequency components;
- and
- means for selecting one of the odd harmonic frequency components of the second signal, wherein the output signal has a frequency substantially equal to the frequency of the selected odd harmonic frequency component.
