  2. Clipping (signal processing) - Wikipedia

    en.wikipedia.org/wiki/Clipping_(signal_processing)

    In the frequency domain, clipping produces strong harmonics in the high-frequency range (as the clipped waveform comes closer to a squarewave).The extra high-frequency weighting of the signal could make tweeter damage more likely than if the signal was not clipped.

  3. Clipping (audio) - Wikipedia

    en.wikipedia.org/wiki/Clipping_(audio)

    The simplest circuits act like a fast limiter, which engages about one decibel before the clipping point. A more complex circuit, called "soft-clip", has been used from the 1980s onward to limit the signal at the input stage. The soft-clip feature begins to engage prior to clipping, for instance starting at 10 dB below maximum output power.

    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.

    The surge is defined by the Combination Wave Generator's open-circuit voltage and short-circuit current waveforms, characterized by front time, duration, and peak values. With an open circuit output, the surge voltage is a double exponential pulse in the form of k ( e − α t − e − β t ) {\displaystyle k(e^{-\alpha t}-e^{-\beta t})} .

    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 ...

  9. Clipper (electronics) - Wikipedia

    en.wikipedia.org/wiki/Clipper_(electronics)

    Voltage clipping limits the voltage to a device without affecting the rest of the waveform. In electronics, a clipper is a circuit designed to prevent a signal from exceeding a predetermined reference voltage level.
