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 converts a first straight-line waveform into a level-shifted, frequency-doubled second straight-line waveform, multiplies the straight-line segments of the first and second waveforms to provide a first curvilinear waveform, and sums this curvilinear waveform with a scaled version of the first straight-line waveform to realize a second curvilinear waveform with further-reduced harmonics.
