BOOLEAN ALGEBRA, Logic Gates Used in Electronic Circuits

BOOLEAN ALGEBRA In this article, we discusses the theorems that are often used in digital systems, especially in simplifying circuit equations. There are 17 formulas that can be used in simplifying logical equations, 15 formulas known as Boolean formulas and 2 formulas known as De Morgan’s theorem. Boolean Theorem Boolean theorem with a number of… Read More »


LOGICAL CIRCUIT In Recent Modern computers do not operate with decimal numbers. What the computer processes are binary numbers, numbers represented by 0 and 1. In digital systems these two numbers are generated in the form of voltage levels, which are then used to operate logic gates. The logic gate itself basically consists of basic… Read More »

Numbers for Digital System

This article describes the number system and the conversion process between number systems. There are four number systems that can be used : decimal, binary, octal, and hexadecimal. The decimal system is certainly familiar because it is always used every day. For digital techniques used binary and hexadecimal number systems. Decimal Numbers Decimal numbers consist… Read More »

It is understood that moving electrons will produce a magnetic field which of course can be attracted or repelled by other magnetic sources. This condition is used as the basis for making electric motors and simple electric meters to measure currents and voltages. The basic construction of an electric meter is shown in Figure 1.… Read More »

Direct Current (DC)  In DC circuits only involve direct current and voltage, that currents and voltages that do not change with time. The elements in the DC circuit include: Battery Resistance Conductor Wire battery produces e.m.f to move electrons which ultimately produces an electric current. The term “circuit” is very suitable because in this case… Read More »

Definition of Electric Currents Electric current occurs because of the flow of electrons in which each electron has a charge of the same amount. If we have a negatively charged object, it means that the object has an excess of electrons. The degree to which the object is filled is measured by the number of… Read More »
