  2. Biasing - Wikipedia

    en.wikipedia.org/wiki/Biasing

    A graphical representation of the current and voltage properties of a transistor; the bias is selected so that the operating point permits maximum signal amplitude without distortion. In electronics , biasing is the setting of DC ( direct current ) operating conditions (current and voltage) of an electronic component that processes time-varying ...

  3. Bias tee - Wikipedia

    en.wikipedia.org/wiki/Bias_tee

    A bias tee is a three-port network used for setting the DC bias point of some electronic components without disturbing other components. The bias tee is a diplexer.The low-frequency port is used to set the bias; the high-frequency port passes the radio-frequency signals but blocks the biasing levels; the combined port connects to the device, which sees both the bias and RF.

    in which k B is the Boltzmann constant, λ is the free-space wavelength, and σ is the RCS of the target. Range values are tabulated in Table 1 for following targets: a sphere with a radius, a, of 10 cm (σ = π a 2 ), a dihedral corner reflector with facet size, a, of 10 cm (σ = 12 a 4 /λ 2 ), the rear of a car (σ = 20 m 2 ) and for a non ...

  5. Integrated Electronics Piezo-Electric - Wikipedia

    en.wikipedia.org/wiki/Integrated_Electronics...

    Supplying the IEPE sensor with constant current, results in a positive bias voltage, typically between 8 and 12 volts, at the output. The actual measuring signal of the sensor is added to this bias voltage. [1] [2] [3] The supply or compliance voltage of the constant current source should be 24 to 30 V which is about two times the bias voltage ...

  6. Feed forward (control) - Wikipedia

    en.wikipedia.org/wiki/Feed_forward_(control)

    Feedforward control requires a mathematical model of the plant (process and/or machine being controlled) and the plant's relationship to any inputs or feedback the system might receive. Neither open loop control nor teleoperator systems require the sophistication of a mathematical model of the physical system or plant being controlled. Control ...

  7. Bipolar transistor biasing - Wikipedia

    en.wikipedia.org/wiki/Bipolar_transistor_biasing

    A load line diagram, illustrating an operating point in the transistor's active region.. Biasing is the setting of the DC operating point of an electronic component. For bipolar junction transistors (BJTs), the operating point is defined as the steady-state DC collector-emitter voltage and the collector current with no input signal applied.
