A Quick Overview

Digital electronics is the foundation for digital computing and provides elemental knowledge on how circuits, systems and hardware communicate within the computer. The use of digital electronic devices are expanding on an accelerated rate and replacing the conventional analogue machines due to its remarkable features such as high accuracy, fast speed and flexibility. Ranging from miniature circuits to high end computers, the use of digital electronics is tremendous. It is therefore essential for engineers and students to understand the basics and implements the logic and design in consumer electronics and related fields. 

Very large-scale integration (VLSI) is a process of embedding or integrating hundreds of thousands of transistors onto a singular silicon semiconductor microchip. VLSI front end design includes digital design using a hardware description language, for example, Verilog, System Verilog, and VHDL. Furthermore, this stage encompasses design verification via simulation and other verification techniques. The entire process also incorporates designing, which starts with the gates and continues through to design for testability. So, understanding digital electronics is very important in terms of IC fabrication and placement as front-end engineer.

Problem Statement

In an exhibition, there are 8 stalls, numbering from A-H. All these stalls are commercial stalls.

The sale of these stalls is encoded as number system format as some stalls understand octal number system and some are hexadecimal etc.

Follow the instructions and perform:

(i) Convert the sale of all stalls in decimal number system.

(ii) Arrange the stalls as per increasing order of sale, as per 0-7 number.

(iii) The stalls whose sale is less than 100 rupees are declared as ‘under performers’. 

(iv) Construct the minterms, SOP, canonical as well as standard form

(v) Design and simplify it using Karnaugh Map or Boolean algebra.

(vi) Implement the desired function using logic gates.

Project 2

Highlights

In a class of 16 students, ranging from roll number 0 to 15. A test of general knowledge was conducted. In which, roll number 15, did not appear, so zero mark was assigned to him. The rest of the class students, appeared in the test.

The result of the test, is related to their roll numbers.

(a) Even roll number students got the marks as ‘n+1’, where n is their roll numbers.

(b) Odd roll number students got the marks as ‘n-1’, where n is their roll numbers

(c) If any unused or overused state is present, just make it ‘0’.

(i) State diagram /State graph

(ii) State table and state transition diagram

(iii) Function using Karnaugh map

(iv) Implement the whole system using D flip-flop
