Introduction To Digital System and Numbering System

A numeral system (or system of numeration) is a mathematical notation for representing a set of numbers by symbols in a consistent manner. It can be seen as the context that allows the numeral “11” to be interpreted as the binary numeral for three, the decimal numeral for eleven, or other numbers in different bases. Ideally, a …

What Are The Types of Digital Signals?

Representation of Digital Signals Digital systems do not store numbers the way humans do. A human can remember the number 4.5 and understand that it represents a quantity. The digital system does not have this capability. Instead, digital systems work with numbers using millions of tiny switches called transistors. Each transistor can remember only one …

Binary Conversion In Digital System and Numbering System

Binary Conversion Unsigned Binary Counting The simplest form of numeric representation with bits is unsigned binary. When we count upward through the positive integers using decimal, we start with a 0 in the one’s place and increment that value until we reach the upper limit of a single digit, i.e., 9. At that point, we’ve …

What is BCD Numeral System?

Binary-Coded Decimal (BCD) is an encoding for decimal numbers in which each digit is represented by its own binary sequence. Its main virtue is that it allows easy conversion to decimal digits for printing or display and faster decimal calculations. Its drawbacks are the increased complexity of circuits needed to implement mathematical operations and a relatively …

Introduction to Logic Gates

Unless you are an electrical engineer, an understanding of the operation of transistors is unnecessary. One level above the transistors, however, is a set of basic building blocks for digital circuitry. These building blocks are called logic gates, and it is at this level that we will begin our discussion. A logic gate has the basic format shown below in the …
