  2. 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). The resulting waveforms can be injected into a device under test and ...

  3. Signal generator - Wikipedia

    en.wikipedia.org/wiki/Signal_generator

    An arbitrary waveform generator (AWG or ARB) is a sophisticated signal generator that generates arbitrary waveforms within published limits of frequency range, accuracy, and output level. Unlike a function generator that produces a small set of specific waveforms, an AWG allows the user to specify a source waveform in a variety of different ways.

  4. Direct digital synthesis - Wikipedia

    en.wikipedia.org/wiki/Direct_digital_synthesis

    A DDS function generator. Direct digital synthesis ( DDS ) is a method employed by frequency synthesizers used for creating arbitrary waveforms from a single, fixed-frequency reference clock. DDS is used in applications such as signal generation , local oscillators in communication systems, function generators , mixers, modulators , [ 1 ] sound ...

  5. Function generator - Wikipedia

    en.wikipedia.org/wiki/Function_generator

    A simple analog function generator, circa 1990 A DDS function generator Sine, square, triangle, and sawtooth waveforms. 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.

  6. Digital pattern generator - Wikipedia

    en.wikipedia.org/wiki/Digital_pattern_generator

    A digital pattern generator is a piece of electronic test equipment or software used to generate digital electronic stimuli. Digital electronics stimuli are a specific kind of electrical waveform varying between two conventional voltages that correspond to two logic states ("low state" and "high state", "0" and "1").

  7. 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.

  8. Waveform - Wikipedia

    en.wikipedia.org/wiki/Waveform

    A sine, square, and sawtooth wave at 440 Hz A composite waveform that is shaped like a teardrop. A waveform generated by a synthesizer. In electronics, acoustics, and related fields, the waveform of a signal is the shape of its graph as a function of time, independent of its time and magnitude scales and of any displacement in time.

  9. 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.
