Englisch - Englisch
{i} (Photography) method of checking a meter on a camera
{i} method of connecting transistors with integrated circuits (Computers, Electronics)
Abbreviation for transistor-transistor logic An old logic family
Transistor Transistor Logic was the initial implementation of the 74xxnnn series logic (TTL being the form with xx omitted)
Through-the-lens metering - Metering that calculates the light coming into the camera from the subject Often used for flashes
An output signal format defined as a rectangular wave capable of driving a multiple of TTL loads It has a positive signal peak greater than +2 4 volts and a negative signal peak less than +0 5 volts The number of loads must be specified (MIL-PRF-55310D, 3 6 20)
Transistor - Transistor Logic
TOP Through-the-lens; commonly used when referring to metering through the lens as opposed to via a separate meter Effective for fill-flash and other tricky lighting situations
Abbreviation for transistor-transistor-logic A popular logic circuit family that uses multiple-emitter transistors A low signal state is defined as a signal 0 8V and below A high signal state is defined as a signal +2 0V and above
Metering system in which light-sensitive cells within the camera body measure exposure from image-forming light that has passed through the lens
An integrated circuit family that use bipolar junction transistors to build the logic gates
Transistor-Transistor Logic; a fast, reasonable-cost type of integrated circuit used in some monitors
Time to Live
Transistor-transistor-logic; logic Zero = <0 8VDC, logic One = >2 4VDC, and will source 1 6 mA
Abbreviation for transistor-transistor logic
See: Time to Live [RFC 1983]
Transistor-transistor logic TTL logic levels are 0V (low) and +5V (high) The TTL switching threshold is around +1 3V (+2V max) When TTL signals are transmitted using coaxial cables, a 10k-ohm termination to ground is typically used Sometimes 50-ohm drivers are used to transmit fast pulses
Transistor-Transistor Logic
a 32 bit signed integer that specifies the time interval that the resource record may be cached before the source of the information should again be consulted Zero values are interpreted to mean that the RR can only be used for the transaction in progress, and should not be cached For example, SOA records are always distributed with a zero TTL to prohibit caching Zero values can also be used for extremely volatile data
A camera design that let's you compose an image while looking at the scene through the lens that will take the picture Also called thru-the-lens
Abbreviation for through the lens, as in through-the-lens viewing or metering

One of the more common logic families in use today Other logic families include CMOS (complementary metal oxide semiconductor) and ECL (emitter-coupled logic) Different logic families are distinguished by such electrical characteristics as logic levels, input current, speed, power consumption, and the supply voltage required
transistor transistor logic
(Through The Lens) An autofocus or autoexposure system that works through the camera's lens
