Data should be encrypted before being transmitted, The receiver should receive the data without any, The mechanism should be able to work even in, The room should be able to detect and display the number of people inside, It should keep a track of when someone enters the room and when someone leaves, The number of lights turning on in the room should be proportional to the number of people in, The room should monitor temperature and maintain it at a preset level by switching a fan on and, The room should monitor the light levels outside and should open blinds and switch of lights if brightness outside is more than inside, provided the user has allowed, Any other intelligent things the room can, Implement a four way intersection with an intelligent traffic regulation method, The time a signal is green should depend on the number of cars waiting at the, The signal should allow for switching between normal and VIP crossing, The signal should implement pedestrian crossing as, The signal should also be able to detect if a person tries cross at a red light and should raise an, The calculator should be purely digital in, It should be able to do addition, subtraction, multiplication and division, The display should be a 2 row one with at least 5, There should be a display for the operation being performed, Each lift should be able to display its location and direction of motion, Each lift should detect number of people entering and should not move if the number exceeds maximum, If two lifts are moving in the same direction and one of them has to stop at a floor to pick someone up, the one with the lesser people inside will, Parking should have a main entrance and should be split into at least 3. We will discuss each one in detail and we will also solve some examples. 5 - 4-to-1 Linr Multiplexer. an Exclusive OR circuit as we have discussed in the introduction part, and a few details of exclusive NOR is also provided and left as an exercise for the reader. Isn’t it simple? Various measurement and analysis instruments can also be implemented in the circuit. GATE ECE Digital Circuits's Number System and Code Convertions, Boolean Algebra, Logic Gates, Combinational Circuits, Sequential Circuits, Semiconductor Memories, Logic Families, Analog to Digital and Digital to Analog Converters Previous Years Questions subject wise, chapter wise and year wise with full detailed solutions provider ExamSIDE.Com For ease of designing and understanding, Digital Circuits are divided into following 2 Types: 1. Expressing a Boolean function in SOP or POS is called Canonical form. As you know for the Minterms we select 1’s in the truth table while for the Maxterms we select 0’s in the truth table. There are certain rules that you need to follow while constructing a logic circuit from any truth table. List of Digital logic design projects LED Cube: A cube of multiplexed LEDs generating 3D patterns. All AND terms are connected to an M-input OR gate, where M is the number of ‘1’ output rows. The interface lets you design … A sheet showing Boolean theorems will be provided. design combinational logic circuits • Combinational logic circuits do not have an internal stored state, i.e., they have no memory. Come up with a way to serially transmit the ADC converted output of a sensor from one location to another. Prerequisites A basic idea regarding the initial concepts of Digital Electronics is enough to understand the topics covered in this tutorial. Program for Decimal to Binary Conversion. For Maxterms consider 0’s in the truth table given above. A Module may be used to built more complex circuits … A mixed-signal integrated circuit is any integrated circuit that has both analog circuits and digital circuits on a single semiconductor die. Computers perform calculations using components called logic gates. Under the management of digital electronic equipment and microprocessors, newer automobiles have added safety features, are more energy efficient, and are easier to diagnose and correct when any fault arise. As an example, consider the XOR relationship YSOP: This SOP relationship can be expressed in POS form as: In this example, the POS and SOP forms are equally simple, but this is not always the case.
