  2. Pulsed DC - Wikipedia

    en.wikipedia.org/wiki/Pulsed_DC

    Pulsed DC (PDC) or pulsating direct current is a periodic current which changes in value but never changes direction. Some authors use the term pulsed DC to describe a signal consisting of one or more rectangular ("flat-topped"), rather than sinusoidal, pulses. [1] Pulsed DC is commonly produced from AC (alternating current) by a half-wave ...

  3. Pulse (signal processing) - Wikipedia

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

    Examples of pulse shapes: (a) rectangular pulse, (b) cosine squared (raised cosine) pulse, (c) Dirac pulse, (d) sinc pulse, (e) Gaussian pulse. A pulse in signal processing is a rapid, transient change in the amplitude of a signal from a baseline value to a higher or lower value, followed by a rapid return to the baseline value. [1]

  4. Output signal switching device - Wikipedia

    en.wikipedia.org/wiki/Output_Signal_Switching_Device

    The device usually acts as the interface of a sensor (such as a light curtain), designed to signal a safety-related event, typically when the light curtain beam's being "broken". OSSD signals are the outputs from the protective device (light curtain or scanner) to a safety relay. OSSD outputs are typically semiconductor or transistor outputs ...

  5. Digital signal - Wikipedia

    en.wikipedia.org/wiki/Digital_signal

    In digital electronics, a digital signal is a pulse amplitude modulated signal, i.e. a sequence of fixed-width electrical pulses or light pulses, each occupying one of a discrete number of levels of amplitude. [6] [7] A special case is a logic signal or a binary signal, which varies between a low and a high signal level.

  6. Dimmer - Wikipedia

    en.wikipedia.org/wiki/Dimmer

    In the electrical schematic shown, a typical light dimmer based on a silicon-controlled rectifier (SCR) dims the light through phase-angle control. This unit is wired in series with the load. Diodes (D2, D3, D4 and D5) form a bridge, which generates pulsed DC. R1 and C1 form a circuit with a time constant.
