  2. 180-degree rule - Wikipedia

    en.wikipedia.org/wiki/180-degree_rule

    180-degree rule. This schematic shows the axis between two characters and the 180° arc on which cameras may be positioned (green). When cutting from the green arc to the red arc, the characters switch places on the screen. In filmmaking, the 180-degree rule[1] is a basic guideline regarding the on-screen spatial relationship between a ...

    The device involves 1.) a vest redistributing the weight of the camera to the hips of the cameraman and, 2.) a spring-loaded arm working to minimize the effects of camera movement. A video tap simultaneously frees the camera operator from the eyepiece, who is then free to travel through any walkable terrain while filming.

  4. Electrical termination - Wikipedia

    en.wikipedia.org/wiki/Electrical_termination

    Electrical termination. In electronics, electrical termination is the practice of ending a transmission line with a device that matches the characteristic impedance of the line. Termination prevents signals from reflecting off the end of the transmission line. Reflections at the ends of unterminated transmission lines cause distortion, which ...

  6. Resistor - Wikipedia

    en.wikipedia.org/wiki/Resistor

    The resistance value is determined by cutting a helix through the coating rather than by etching, similar to the way carbon resistors are made. The result is a reasonable tolerance (0.5%, 1%, or 2%) and a temperature coefficient that is generally between 50 and 100 ppm/K. [ 18 ] Metal film resistors possess good noise characteristics and low ...

  7. Four-terminal sensing - Wikipedia

    en.wikipedia.org/wiki/Four-terminal_sensing

    Four-point measurement of resistance between voltage sense connections 2 and 3. Current is supplied via force connections 1 and 4. In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements ...

  8. Pull-up resistor - Wikipedia

    en.wikipedia.org/wiki/Pull-up_resistor

    When the switch is closed, the input voltage at the gate goes to ground. In electronic logic circuits, a pull-up resistor (PU) or pull-down resistor (PD) is a resistor used to ensure a known state for a signal. [1] It is typically used in combination with components such as switches and transistors, which physically interrupt the connection of ...

  9. Digital video - Wikipedia

    en.wikipedia.org/wiki/Digital_video

    Digital video is an electronic representation of moving visual images (video) in the form of encoded digital data. This is in contrast to analog video, which represents moving visual images in the form of analog signals. Digital video comprises a series of digital images displayed in rapid succession, usually at 24, 25, 30, or 60 frames per second.
