### Logic AND Function

In 1854, George Boole performed an investigation into the “laws of thought” which were based around a simplified version of the “group” or “set” theory, and from

As we have seen in this Binary Numbers section of tutorials, there are many different binary codes used in digital and electronic circuits, each with

We know that decimal (or denary) numbers use the base ten (base-10) numbering system where each digit in a decimal number is allowed to take one

In mathematics, positive numbers (including zero) are represented as unsigned numbers. That is we do not put the +ve sign in front of them to

The Octal Numbering System is very similar in principle to the previous hexadecimal numbering system except that in Octal, a binary number is divided up into groups

The one main disadvantage of binary numbers is that the binary string equivalent of a large decimal base-10 number can be quite long. When working with

However, the numbering system used in one type of circuit may be different to that of another type of circuit, for example, the memory of

Conversion of binary to decimal (base-2 to base-10) numbers and back is an important concept to understand as the binary numbering system forms the basis

Unlike a linear, or analogue circuits, such as AC amplifiers, which process signals that are constantly changing from one value to another, for example amplitude

The Passive Attenuator is a purely resistive network that is used to weaken or “attenuate” the signal level of a transmission line while improving the impedance match,

As its name implies, the bridged-T attenuator has an additional resistive element forming a bridged network across the two series resistors of the standard T-pad. This additional

The Pi-pad attenuator is so called because its basic layout and design resembles that of the Greek letter pi ( π ), meaning that it has one
