  2. Reflections of signals on conducting lines - Wikipedia

    en.wikipedia.org/wiki/Reflections_of_signals_on...

    A time-domain reflectometer; an instrument used to locate the position of faults on lines from the time taken for a reflected wave to return from the discontinuity.. A signal travelling along an electrical transmission line will be partly, or wholly, reflected back in the opposite direction when the travelling signal encounters a discontinuity in the characteristic impedance of the line, or if ...

  3. Proper zero-signal collector current - Wikipedia

    en.wikipedia.org/wiki/Proper_zero-signal...

    A sufficient battery source in the base circuit keeps the input circuit forward biased even during the peak of the negative half-cycle. When no signal is applied, a DC current I C will flow in the collector circuit due to the battery. This is known as zero signal collector current. [1]

  4. Charge amplifier - Wikipedia

    en.wikipedia.org/wiki/Charge_amplifier

    The charge signals at the input of a charge amplifier can be as low as some fC (FemtoCoulomb = 10 −15 C). A parasitic effect of common coaxial sensor cables is a charge shift when the cable is bent. Even slight cable motion may produce considerable charge signals which cannot be distinguished from the sensor signal.

  5. Signal conditioning - Wikipedia

    en.wikipedia.org/wiki/Signal_conditioning

    Signal conditioning. In electronics and signal processing, signal conditioning is the manipulation of an analog signal in such a way that it meets the requirements of the next stage for further processing. In an analog-to-digital converter (ADC) application, signal conditioning includes voltage or current limiting and anti-aliasing filtering .

    A concussion is a mild form of traumatic brain injury, or TBI. It occurs when the skull and brain are rapidly jolted back and forth. This is usually the result of a bump, bang, or blow to the head ...

  8. Electromagnetic interference - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_interference

    Electromagnetic interference ( EMI ), also called radio-frequency interference ( RFI) when in the radio frequency spectrum, is a disturbance generated by an external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction. [1] The disturbance may degrade the performance of the circuit or ...

  9. Error analysis for the Global Positioning System - Wikipedia

    en.wikipedia.org/wiki/Error_analysis_for_the...

    For long delay multipath, the receiver itself can recognize the wayward signal and discard it. To address shorter delay multipath from the signal reflecting off the ground, specialized antennas (e.g., a choke ring antenna) may be used to reduce the signal power as received by the antenna. Short delay reflections are harder to filter out because ...
