# Decimal To BCD Encoder In Digital Electronics

A decimal to bcd encoder has 10 input lines D0 to D9 and 4 output lines Y0 to Y3. Below is the truth table for a decimal to bcd encoder. From the truth table, the outputs can be expressed by Continue reading

# Octal To Binary Encoder In Digital Electronics

An encoder has 2n or fewer input lines, only one of which is in the “1” state at a particular time and an n-bit code is generated on “n” output lines depending upon which of the input is excited.  In Continue reading

# 3-Variable K-Map – Karnaugh Map In Digital Electronics Tutorial Part 4

A 3-variable K-Map will have 23 = 8 cells. As told in last post, number of variables are decided by the biggest decimal number in a given function.  A function F which has maximum decimal value of 7, can be Continue reading

# Rules of Simplifying Karnaugh Map – Karnaugh Map In Digital Electronics Tutorial Part 3

Looping adjacent 1’s for simplification The expression for output Y can be simplified by properly combining those squares in the K-Map which contain 1s. The process of combining those 1s is called looping. Pairs – Looping groups of Two 1s Continue reading

# Understanding Minterms and Maxterms In Digital Electronics – Karnaugh Map In Digital Electronics Tutorial Part 2

Understanding Minterms A binary variable may appear in its normal form (as A) or in its complemented form (as A’). If we consider two variables such as A and B combined by an AND operation, then there are four possible Continue reading

# Karnaugh Map In Digital Electronics Tutorial Part 1

Karnaugh Map, very commonly know as K-Map is a graphical device used to simplify a logic equation or to convert a truth table to its corresponding logic circuit in a simple orderly process. K-map is like a truth table, which shows Continue reading

# Up Down Counter in Digital Electronics

A counter which can be made to count in either the forward or reverse direction is called an up-down, a reversible or forward-backward counter. Down Counter A binary counter with a reverse count is called a binary down counter. In Continue reading
