Waveform, (b) the spectrum, and (c) the harmonic magnitude error of the PD model of the Moog sawtooth oscillator output,that is, the difference between the model output harmonic magnitudes and the magnitudes ... phasetrajectory of the reset portion of a recorded waveform. Since the recorded waveforms have their maxima close to the end of the oscillation period (see Figures 1(a) and 2(a)), the phasetrajectory of the...
