  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. 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. Sweep generator - Wikipedia

    en.wikipedia.org/wiki/Sweep_generator

    Sweep generator in Lawrence Livermore National Laboratory, 1950. A sweep generator is a piece of electronic test equipment similar to, and sometimes included on, a function generator which creates an electrical waveform with a linearly varying frequency and a constant amplitude.

  5. Direct digital synthesis - Wikipedia

    en.wikipedia.org/wiki/Direct_digital_synthesis

    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 synthesizers and as part of ...

  6. Master frequency generator - Wikipedia

    en.wikipedia.org/wiki/Master_frequency_generator

    A master frequency generator or master electronic oscillator, in frequency-division multiplexing (FDM), is a piece of equipment used to provide system end-to-end carrier frequency synchronization and frequency accuracy of tones. The following types of oscillators are used in the Defense Communications System FDM systems:

  7. Comb generator - Wikipedia

    en.wikipedia.org/wiki/Comb_generator

    An optical comb generator can be used as generators of terahertz radiation. Internally, it is a resonant electro-optic modulator , with the capability of generating hundreds of sidebands with total span of at least 3 terahertz (limited by the optical dispersion of the lithium niobate crystal) and frequency spacing of 17 GHz.
