The binary numeral system‚ or base-2 number system‚ represents numeric values using two symbols‚ 0 and 1. More specifically‚ the usual base-2 system is a positional notation with a radix of 2. Because of its straightforward implementation in digital electronic circuitry using logic gates‚ the binary system is used internally by almost all modern computers. Why Computers Use Binary Binary numbers – seen as strings of 0’s and 1’s – are often associated with computers. But why is this? Why

True/False Indicate whether the statement is true or false. 1. The voltages in digital electronics are continuously variable. False 2. A digital system with 4 inputs can have any input combination represented by a hexadecimal numeral. True 3. Frequency is the number of times that a periodic waveform repeats per second. True 4. The period of a waveform can be found by 1/frequency. True 5. The falling edge of a signal is the transition from a HIGH to a LOW. True 6. The

DECIMAL FORMATS INTRODUCTION HOW DOES A COMPUTER REPRESENT THE NUMERICAL DATA IN BINARY FORMAT? Base-2 digits [Straight Binary] BCD [Binary-Coded Decimal] binary-coded decimal (BCD) - class of binary encodings of decimal numbers In byte-oriented systems (i.e. most modern computers)‚ the term uncompressed BCD usually implies a full byte for each digit (often including a sign)‚ whereas packed BCD typically encodes two decimal digits within a single byte by taking advantage of the fact that four bits

Although digital computers differ greatly in size they all have five basic parts: input equipment‚ main memory‚ the control unit‚ arithmetic/logic unit‚ output equipment. All data handled by digital computers‚ including words‚ are in form of digits. But the computers use only the two digits of binary number system – that is‚ 0 and 1. Different combinations

NUMBER NUMBER SYSTEMS • Decimal 0~9 • Binary 0~1 • Octal 0~7 • Hexadecimal 0~F DECIMAL DECIMAL The decimal system is composed of 10 numerals or symbols. These 10 symbols are 0‚ 1‚ 2‚ 3‚ 4‚ 5‚ 6‚ 7‚ 8‚ 9; using these symbols as digits of a number‚ we can express any quantity. The decimal system‚ also called the base-10 system because it has 10 digits. EXAMPLE: 47 = (4 X 101)+(7 X 100) = (4 X 10) + (7 X 1) = 40+ 7 EXERCISE : 568.23 = BINARY BINARY In the binary system‚ there are only

numbers that are greater or equal to zero‚ an "excess" value of six results in the sum. Since a four bit integer can only hold values 0 to 15‚ an excess of six means that any sum over nine will overflow. A code converter is a circuit that makes the two systems compatible even though each uses a different binary code. Our project is to convert a user entered BCD number into Excess-3 using 4:1 MUX. We chose to use multiplexer so as to simplify the circuit and reduce the use of more number of IC’s. channel

Writing systems are distinguished from other possible symbolic communication systems in that one must usually understand something of the associated spoken language to comprehend the text. By contrast‚ other possible symbolic systems such as information signs‚ painting‚ maps‚ and mathematics often do not require prior knowledge of a spoken language. Every human community
