The rule states that the camera should be kept on one side of an imaginary axis between two characters, so that the first character is always frame right of the second character. Moving the camera over the axis is called jumping the line or crossing the line ; breaking the 180-degree rule by shooting on all sides is known as shooting in the round .
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 ...
Trimmer (electronics) A trimmer, or preset, is a miniature adjustable electrical component. It is meant to be set correctly when installed in some device, and never seen or adjusted by the device's user. Trimmers can be variable resistors (potentiometers), variable capacitors, or trimmable inductors. They are common in precision circuitry like ...
Voltage-controlled resistor. A voltage-controlled resistor (VCR) is a three-terminal active device with one input port and two output ports. The input-port voltage controls the value of the resistor between the output ports. VCRs are most often built with field-effect transistors (FETs). Two types of FETs are often used: the JFET and the MOSFET.
Four dramas. Four networks. 'Matlock,' 'High Potential,' 'Brilliant Minds' and 'Rescue: HI-Surf' showcase the variety, and the ongoing appeal, of broadcast television.
Surface-mount technology (SMT) component placement systems, commonly called pick-and-place machines or P&Ps, are robotic machines which are used to place surface-mount devices (SMDs) onto a printed circuit board (PCB). They are used for high speed, high precision placing of a broad range of electronic components (such as capacitors, resistors ...
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 ...
The signal conductors are positive, both fed through resistors of equal value (6.81 kΩ for 48 V, 1.2 kΩ for 24 V, and 680 Ω for 12 V), and the shield is ground. The 6.81 kΩ value is not critical, but the resistors must be matched to within 0.1% [ 6 ] or better to maintain good common-mode rejection in the circuit.
