In electronics, a multiplexer or mux is a device that selects one of several analog or digital input signals and forwards the selected input into a single line. Using the above Boolean Equation the circuit diagram is drawn as: The logic gates such as And,Not,Or and 3-input And gates implemented using For getting 8 data inputs, we need two 4 × 1 multiplexers. Electronics Mini Projects for Engineering Students: Water Level Controller using 8051 Microcontroller: Here we are designing the circuit which is used to detect and control the water level automatically in overhead tank using 8051 microcontroller. In digital logic, A multiplexer is the logical implementation of a single pole, N position switch. These control lines can be determined by using this formula like 2n=r where ‘r’ is the no of i/p signals & ‘n’ is the no of required control lines. 3.Then, by using the above Boolean Eqaution,construct the circuit Diagram. You have to use a decoder between them to convert (process) a binary signal … The 2 × 1 multiplexer has only 1 selection line. 2.To get the Boolean equation using the truth table b… single common output line by the application of a control signal. Project 2 :- 3-Bit-Flash-Type-Analog-to-Digital-Converter. Project 6 :- AMPLITUDE-MODULATION-AND-DEMODULATION. 1×8 De-multiplexer using 1×4 and 1×2 de-multiplexer. Adder In Digital Electronics-A combinational circuit that performs the addition of bits is called an Adder.Each computer has an adder located in its CPU(ALU) that is responsible for the process of addition.

Digital electronics projects listed here are part of previous year final year projects which are submitted by electronics and communication engineering students. Construct a 6圆圆 or a 7x7x7 LED cube that will be operated through multiplexing When switched on, the cube will display text, patterns etc The cube can be either single colored (easy) or can be made using RGB LEDs (hard) Line following based maze solver The block diagram of 8 × 1 multiplexer using 4 × 1 and 2 × 1 multiplexer is given below. And off course to provide different time duration to each signal. Ultra Sonic Alarm for Visually Impaired Infra-Red Repeater. Harris, ‘Digital Design Description: A Demultiplexer or Demux in digital electronics is a circuit that takes a single input line and routes it to one of several digital output lines. Lots of books on digital electronics, e.g., – D.
