  2. Lecher line - Wikipedia

    en.wikipedia.org/wiki/Lecher_line

    In electronics, a Lecher line or Lecher wires is a pair of parallel wires or rods that were used to measure the wavelength of radio waves, mainly at VHF, UHF and microwave frequencies. [ 1 ] [ 2 ] They form a short length of balanced transmission line (a resonant stub ).

  3. Transposition (transmission lines) - Wikipedia

    en.wikipedia.org/wiki/Transposition...

    By twisting, the wires become longer than the cable. The stranding factor indicates the relationship of single wire length to cable length; it amounts to with communication cables about 1.02 to 1.04. In open wire lines used for long-distance (trunk or toll) telephone circuits, transposition was used for reducing cross-talk. Originally used to ...

  4. 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 ...

    en.wikipedia.org/wiki/Einthoven's_triangle

    Lead II — This axis goes from the right arm to the left leg, with the negative electrode on the shoulder and the positive one on the leg. This results in a +60 degree angle of orientation. [4] = Lead III — This axis goes from the left shoulder (negative electrode) to the right or left leg (positive electrode). This results in a +120 degree ...

  6. Transmission line - Wikipedia

    en.wikipedia.org/wiki/Transmission_line

    At a distance x into the line, there is current I(x) travelling through each wire, and there is a voltage difference V(x) between the wires. If the current and voltage come from a single wave (with no reflection), then V ( x ) / I ( x ) = Z 0 , where Z 0 is the characteristic impedance of the line.

  7. Circular polarization - Wikipedia

    en.wikipedia.org/wiki/Circular_polarization

    A circularly polarized wave can rotate in one of two possible senses: right-handed circular polarization (RHCP) in which the electric field vector rotates in a right-hand sense with respect to the direction of propagation, and left-handed circular polarization (LHCP) in which the vector rotates in a left-hand sense.

  8. Electrical length - Wikipedia

    en.wikipedia.org/wiki/Electrical_length

    In electrical engineering, electrical length is a dimensionless parameter equal to the physical length of an electrical conductor such as a cable or wire, divided by the wavelength of alternating current at a given frequency traveling through the conductor. [1] [2] [3] In other words, it is the length of the conductor measured in wavelengths.

  9. Harmonics (electrical power) - Wikipedia

    en.wikipedia.org/wiki/Harmonics_(electrical_power)

    A set of three line (or line-to-line) voltages in a balanced three-phase (three-wire or four-wire) power system cannot contain harmonics whose frequency is an integer multiple of the frequency of the third harmonics (i.e. harmonics of order =), which includes triplen harmonics (i.e. harmonics of order = ()).
