BCD binary numbers represent Decimal digits 0 to 9. A 4-bit BCD code is used torepresent the ten numbers 0 to 9. Since the 4-bit Code allows 16 possibilities, therefore thefirst 10 4-bit combinations are considered to be valid BCD combinations. The latter sixcombinations are invalid and do not occur.BCD Code has applications in Decimal Number display Systems such as Counters andDigital Clocks. BCD Numbers can be added together using BCD Addition. BCD Addition issimilar to normal Binary Addition except for the case when sum of two BCD digits exc ....etc

Torque Ripple Minimization in a Switched
Reluctance Drive by Neuro-fuzzy
Compensation

Simple power electronic drive circuit and fault tolerance of converter are specific advantages of SRM drives, but excessive torque ripple has limited its use to special applications. A new method for shaping the motor currents so that the ripple can be reduced is presented by this paper. Here, a compensating signal is added to the output of a PI
controller. This is added in a current regulated speed control loop.

Introduction
I.a. Objectives
In this experiment, parallel adders, subtractors and complementors will be
designed and investigated. In the first and second parts of the experiment you will
implement your circuits using ICs and connecting them on the breadboard. In the
rest of the experiment, you will use Quartus 14.1 software and FPGA to
implement the circuits. In this experiment, you need to download your designs to
the FPGA and check the results by physical means, i.e., using LEDs and
oscilloscope. Another objective of this experiment ....etc

Introduction

To be able to perform arithmetic, you must first be familiar with numbers. Therefore, although we give a few helping examples, this article is not about binary numerals.

The main interactive circuit at the top of this page is an arithmetic circuit capable of performing both addition and subtraction on any two 4-bit binary numbers. The circuit has a Mode switch that allows you to choose between adding (M=0) and subtracting (M=1). To understand why t ....etc
