1.2.1 Aliasing-free oscillators
Standard digital synthesizers produce aliasing in high frequencies, and also when using Pulse
Width Modulation or FM.
TAE
®
allows the production of totally aliasing-free oscillators in all contexts (PWM, FM…), and at
no extra CPU cost.

1.2.2 A better reproduction of analog oscillator waveforms
The waveforms produced by the oscillators in analog synthesizers are marked by the presence of
a capacitor in the circuits. The discharge of the capacitor results in a light bend in the original
waveform (notably for saw tooth, triangular and square waveforms). TAE
®
allows the
reproduction of this capacitor discharge. This is the analysis of a waveform from the original
Prophet 5, and that of the Prophet V. They are both equally deformed by the Prophet V low-
pass and high—pass filtering.
