  2. Multiplexer - Wikipedia

    en.wikipedia.org/wiki/Multiplexer

    For example, an 8-to-1 multiplexer can be made with two 4-to-1 and one 2-to-1 multiplexers. The two 4-to-1 multiplexer outputs are fed into the 2-to-1 with the selector pins on the 4-to-1's put in parallel giving a total number of selector inputs to 3, which is equivalent to an 8-to-1.

  3. Adder–subtractor - Wikipedia

    en.wikipedia.org/wiki/Adder–subtractor

    By preceding each A input bit on the adder with a 2-to-1 multiplexer where: Input 0 (I 0) is A; Input 1 (I 1) is A; that has control input D that is also connected to the initial carry, then the modified adder performs addition when D = 0, or; subtraction when D = 1. This works because when D = 1 the A input to the adder is really A and the

  7. Multiplex locomotive - Wikipedia

    en.wikipedia.org/wiki/Multiplex_locomotive

    A multiplex locomotive is a steam locomotive that divides the driving force on its wheels by using multiple pairs of cylinders to drive multiple driving wheel set groups. Such a locomotive will necessarily articulated if it has more than two sets of driving wheels. There were locomotive projects with three, four, five or six sets of drive wheels.

    The light then traverses another free space (4) and interferes at the entries of the output waveguides (5) in such a way that each output channel receives only light of a certain wavelength. The orange lines only illustrate the light path. The light path from (1) to (5) is a demultiplexer, from (5) to (1) a multiplexer.

  9. Charlieplexing - Wikipedia

    en.wikipedia.org/wiki/Charlieplexing

    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.
