Multiplexer; Like a scan configuration, multiplex switching can be used to connect one instrument to multiple devices (1:N) or multiple instruments to a single device (N:1), but it offers much more flexibility than the scanner configuration because it permits multiple simultaneous connections and both sequential and non-sequential switch closures.
First, the switch matrix receives the data bus signals, then provides the proper switching and signal conditioning for the signals before feeding the signals to the test and measurement instruments. This custom switch matrix would employ 14 EM switches and a number of different signal conditioners including: power splitters, amplifiers, mixers ...
The DMS-100 is a member of the Digital Multiplex System (DMS) product line of telephone exchange switches manufactured by Northern Telecom. Designed during the 1970s and released in 1979, it can control 100,000 telephone lines. [1] The purpose of the DMS-100 Switch is to provide local service and connections to the PSTN public
An RF switch or microwave switch is a device to route high frequency signals through transmission paths. RF ( radio frequency ) and microwave switches are used extensively in microwave test systems for signal routing between instruments and devices under test (DUT).
A Charlieplexed digital clock which controls 90 LEDs with 10 pins of a PIC 16C54 microcontroller.. Charlieplexing (also known as tristate multiplexing, reduced pin-count LED multiplexing, complementary LED drive and crossplexing) is a technique for accessing a large number of LEDs, switches, micro-capacitors or other I/O entities, using relatively few tri-state logic wires from a microcontroller.
In electronics, a crossover switch or matrix switch is a switch connecting multiple inputs to multiple outputs using complex array matrices designed to switch inputs to outputs such that each output is connected to only one input, but usually inputs may be connected to multiple outputs. There are blocking and non-blocking types of cross-over ...
The basic concept of the third state, high impedance (Hi-Z), is to effectively remove the device's influence from the rest of the circuit. If more than one device is electrically connected to another device, putting an output into the Hi-Z state is often used to prevent short circuits, or one device driving high (logical 1) against another device driving low (logical 0).
The DMS name arose from a designation for a switching matrix design that was developed in the exploratory phase of the project. The Digital Multiplexed Switch was selected as the basic switching design for the project. The product was intended as a successor for Nortel's first electronic switch, the SP1, and was to be called the SP2. However ...
