2. Function generator - Wikipedia

   en.wikipedia.org/wiki/Function_generator

   In electrical engineering, a function generator is usually a piece of electronic test equipment or software used to generate different types of electrical waveforms over a wide range of frequencies. Some of the most common waveforms produced by the function generator are the sine wave, square wave, triangular wave and sawtooth shapes.

3. Signal generator - Wikipedia

   en.wikipedia.org/wiki/Signal_generator

   A signal generator is one of a class of electronic devices that generates electrical signals with set properties of amplitude, frequency, and wave shape. These generated signals are used as a stimulus for electronic measurements, typically used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices, though it often has artistic uses as well.

4. Sine wave - Wikipedia

   en.wikipedia.org/wiki/Sine_wave

   A sine wave, sinusoidal wave, or sinusoid (symbol: ∿) is a periodic wave whose waveform (shape) is the trigonometric sine function. In mechanics , as a linear motion over time, this is simple harmonic motion ; as rotation , it corresponds to uniform circular motion .

5. Additive synthesis - Wikipedia

   en.wikipedia.org/wiki/Additive_synthesis

   Schematic diagram of additive synthesis. The inputs to the oscillators are frequencies and amplitudes .. Harmonic additive synthesis is closely related to the concept of a Fourier series which is a way of expressing a periodic function as the sum of sinusoidal functions with frequencies equal to integer multiples of a common fundamental frequency.

6. Unit generator - Wikipedia

   en.wikipedia.org/wiki/Unit_generator

   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. The example ...

7. Intersil ICL8038 - Wikipedia

   en.wikipedia.org/wiki/Intersil_ICL8038

   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.
