Introduction We are all familiar with the word “register”, yes, the same which we use in our schools days. That register is a place we write our day-to-day notes, and these notes get stored permanently in this register. So we define such register as a group of pages used to store characters. This register come...

Sequential Circuit

Ravinder Nath Rajotiya — Wed, 18 Oct 2023 06:34:32 +0000

Introduction In the previous posts we have focused on the design of many combinational circuits. The outputs in those circuits were dependent on the inputs applied at that instant of taking the output. Examples of such circuits were adders like half and full adders, half and full subtractors, BCD adders, Multiplexers, decoders , etc. But...

Introduction to Counters I remember my childhood, at a time even before going to the primary school, we used to play with pebbles, soon we started counting the pebbles. When I joined school, I realized that counting is part of our life and is used in every walk of life, count starting from zero, or...

Flip-Flop and Latches

Introduction The second type of digital circuitry are the sequential circuits. These circuitry are formed as a combination of combinational and the memory element. The memory element stores the state of the circuit. We start discussing on Latches and Flip-Flops. Latches Storage elements that operate with signal levels (i.e. level triggered of signal input) are...

Adder Circuits

Ravinder Nath Rajotiya — Sun, 17 Sep 2023 17:12:03 +0000

Introduction In this article we will discuss the design of the arithmetic adder and subtracter circuits. These circuits will take input bits and produce two outputs sum and carry or difference and borrow. Half adder A half adder is a logic circuit that adds two bits at a time. These two bits may be the...
