A completely different approach to function generation is to use software instructions to generate a waveform, with provision for output. For example, a general-purpose digital computer can be used to generate the waveform; if frequency range and amplitude are acceptable, the sound card fitted to most computers can be used to output the generated wave.
Intersil ICL8038 ICL8038 operation (simplified; sine wave is derived from the triangular wave). The ICL8038 waveform generator was an Integrated circuit by Intersil designed to generate sine, square and triangular waveforms, [1] based on bipolar monolithic technology involving Schottky barrier diodes.

Sinewave synthesis, or sine wave speech, is a technique for synthesizing speech by replacing the formants (main bands of energy) with pure tone whistles. The first sinewave synthesis program ( SWS ) for the automatic creation of stimuli for perceptual experiments was developed by Philip Rubin at Haskins Laboratories in the 1970s.
Additive synthesis is a sound synthesis technique that creates timbre by adding sine waves together. [1] [2]The timbre of musical instruments can be considered in the light of Fourier theory to consist of multiple harmonic or inharmonic partials or overtones.
By just amplitude-modulating these two 90°-out-of-phase sine waves and adding them, it is possible to produce the effect of arbitrarily modulating some carrier: amplitude and phase. A phasor for I/Q, and the resultant wave which is continually phase shifting, according to the phasor's frequency. Note that since this resultant wave is ...
In psychoacoustics, a pure tone is a sound with a sinusoidal waveform; that is, a sine wave of constant frequency, phase-shift, and amplitude. [1] By extension, in signal processing a single-frequency tone or pure tone is a purely sinusoidal signal (e.g., a voltage).
A Wien bridge oscillator is a type of electronic oscillator that generates sine waves. It can generate a large range of frequencies. The oscillator is based on a bridge circuit originally developed by Max Wien in 1891 for the measurement of impedances. [1] The bridge comprises four resistors and two capacitors.
Unit generators often use predefined arrays of values for their functions (which are filled with waveforms or other shapes by calling a specific generator function). In the SuperCollider language, the .ar method in the SinOsc class [ 6 ] inherits methods from an overarching unit generator class (UGen) [ 3 ] that generates a sine wave .
