A geometrical waveform typically generated by an oscillator. It is triangular in shape and comprises the same sequence of only odd numbered (1, 3, 5, 7, etc.) harmonic partials as the square wave, but as the amplitude of each harmonic is the reciprocal of the square of the harmonic number (i.e. the 3rd. harmonic is a 9th. the amplitude of the 1st.)...
