Chapter 7 Numbering Systems and Codes

Mica capacitors normally use a(n) ___ dot system.

six

As many as ___ digits could change for a single count when using the binary numbering system.

4

The United States monetary system is based on the octal numbering system.

False

The binary coded decimal (BCD) system is a coding system that represents each digit from zero through nine as a eight-bit binary number.

False

____ are devices that limit the current flowing in an electronic circuit.

Resistors

A word is a group of one or more bytes (1111000011110000, etc).

True

Capacitor color codes are standardized by the Electronic Industries Association (EIA).

True

Digital electronic systems use the binary numbering system because it uses the digits 0 and 1, which are used to represent the two physical states that most electrical elements have (ON/OFF, open/closed, etc).

True

Prefixes and exponents may be used to simplify the expression of large decimal numbers.

True

The first two color bands represent the first two digits in the value of a resistor.

True

The fourth band indicates how far the actual measured value of a resistor can be from the coded value.

True

The ___ numbering system is a base two numbering system that uses only two digits, 0 and 1.

binary

to convert a decimal number to a(n) ___ number, the decimal number is divided by 2 in repetitive steps.

binary

A ___ is each digit (0 or 1) of a binary number.

bit

A(n) ___ is a group of 8 bits (10001101, etc).

byte

A(n) ___ number is a number expressed in base 10.

decimal

The ___ numbering system is the most commonly used numbering system.

decimal

In the ___ code, only one digit changes for each count from one number to the next.

gray

The ___ numbering system is a base 16 numbering system that uses digits 0,1,2,3,4,5,6,7,8,9, and the first six letters of the alphabet, A,B,C,D,E,F.

hexadecimal

For tubular ceramic capacitors, the wide color band specifying temperature coefficient indicates the ___ end.

left

A(n) ___ is a group of 4 bits (1001, 0011, etc).

nibble

The ___ numbering system is a base eight numbering system that uses only digits 00,1,2,3,4,5,6,7.

octal

Color-coded capacitance values are always in ___ units.
