  2. Function generator - Wikipedia

    en.wikipedia.org/wiki/Function_generator

    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.

  3. Additive synthesis - Wikipedia

    en.wikipedia.org/wiki/Additive_synthesis

    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.

  4. 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. [2]

  5. 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.

  6. Pure tone - Wikipedia

    en.wikipedia.org/wiki/Pure_tone

    A pure tone's pressure waveform versus time looks like this; its frequency determines the x axis scale; its amplitude determines the y axis scale; and its phase determines the x origin. 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]

  7. Arbitrary waveform generator - Wikipedia

    en.wikipedia.org/wiki/Arbitrary_waveform_generator

    An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms. [ 1 ] [ 2 ] [ 3 ] These waveforms can be either repetitive or single-shot (once only) in which case some kind of triggering source is required (internal or external).

  8. Pulse-width modulation - Wikipedia

    en.wikipedia.org/wiki/Pulse-width_modulation

    SPWM (sine–triangle pulse-width modulation) signals are used in micro-inverter design (used in solar and wind power applications). These switching signals are fed to the FETs that are used in the device. The device's efficiency depends on the harmonic content of the PWM signal.

  9. Wien bridge oscillator - Wikipedia

    en.wikipedia.org/wiki/Wien_bridge_oscillator

    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.
