<p>Simple, inexpensive waveform generators and methods are provided that generate curvilinear waveforms which comprise a fundamental sinusoid and harmonics that are either absent or are significantly reduced from the fundamental. In an exemplary method, a generator (120) converts a first straight-line waveform (22) into a level shifted, frequency-doubled second straight-line waveform (24), multiplies the straight-line segments of the first and second waveforms to provide a first curvilinear waveform (26), and sums this curvilinear waveform with a scaled version of the first straight-line waveform to realize a second curvilinear waveform (30) with further-reduced harmonics.</p> |
