  2. Electromyography - Wikipedia

    en.wikipedia.org/wiki/Electromyography

    Two types of rectification are used: full-wave and half-wave rectification. [27] Full-wave rectification adds the EMG signal below the baseline to the signal above the baseline to make a conditioned signal that is all positive. If the baseline is zero, this is equivalent to taking the absolute value of the signal. [28] [29] This is the ...

  3. Envelope detector - Wikipedia

    en.wikipedia.org/wiki/Envelope_detector

    Between the circuit's input and output is a diode that performs half-wave rectification, allowing substantial current flow only when the input voltage is around a diode drop higher than the output terminal. The output is connected to a capacitor of value and resistor of value in parallel to ground. The capacitor is charged as the input voltage ...

  4. Pulsed DC - Wikipedia

    en.wikipedia.org/wiki/Pulsed_DC

    Pulsed DC is commonly produced from AC (alternating current) by a half-wave rectifier or a full-wave rectifier. Full wave rectified ac is more commonly known as Rectified AC. PDC has some characteristics of both alternating current (AC) and direct current (DC) waveforms. The voltage of a DC wave is roughly constant, whereas the voltage of an AC ...

  5. Ripple (electrical) - Wikipedia

    en.wikipedia.org/wiki/Ripple_(electrical)

    The characteristics and components of ripple depend on its source: there is single-phase half- and full-wave rectification, and three-phase half- and full-wave rectification. Rectification can be controlled (uses Silicon Controlled Rectifiers (SCRs)) or uncontrolled (uses diodes). There is in addition, active rectification which uses transistors.

  6. Active rectification - Wikipedia

    en.wikipedia.org/wiki/Active_rectification

    Active full-wave rectification with two MOSFETs and a center tap transformer. Replacing a diode with an actively controlled switching element such as a MOSFET is the heart of active rectification. MOSFETs have a constant very low resistance when conducting, known as on-resistance (R DS(on)). They can be made with an on-resistance as low as 10 ...

  7. Experimental psychology - Wikipedia

    en.wikipedia.org/wiki/Experimental_psychology

    Experimental psychology refers to work done by those who apply experimental methods to psychological study and the underlying processes. Experimental psychologists employ human participants and animal subjects to study a great many topics, including (among others) sensation, perception, memory, cognition, learning, motivation, emotion; developmental processes, social psychology, and the neural ...

  8. Valley-fill circuit - Wikipedia

    en.wikipedia.org/wiki/Valley-fill_circuit

    For purposes of illustration, a basic full-wave diode-bridge rectifier is shown in the first stage, which converts the AC input voltage to a DC voltage. Operation

  9. Mercury-arc valve - Wikipedia

    en.wikipedia.org/wiki/Mercury-arc_valve

    Mercury rectifier on display in the Beromünster AM transmitter in Switzerland, before being decommissioned.Three-phase full-wave rectifier with six anodes. A mercury-arc valve or mercury-vapor rectifier or (UK) mercury-arc rectifier [1] [2] is a type of electrical rectifier used for converting high-voltage or high-current alternating current (AC) into direct current (DC).
