Four bits equal one byte.
An inverter performs a NOT operation.
Memory devices store binary data.
A digital circuit will not obey a set of logic rules.
Telecommunications systems do not use digital techniques.
A device to convert a binary number to a 7-segment display format is a decoder.
A graph of phase vs. time is a timing diagram.
Circuits that exhibit the property of memory normally revert to their original state when the input is removed.
A logic analyzer is used to display a timing diagram.
In a positive logic system, the logic LOW could be between 0 V and 0.8 V.
SMT stands for small-to-medium technology.
An ADC is an analog-to-digital converter.
The voltage levels used to represent binary values (0 and 1) in a digital system are nearly equal in value.
The real world is mainly analog.
Binary means having two states or values.
The two binary digits are 1 and 2.
In a negative logic system, a high is represented by 0.
Parallel transmission is faster than serial.
A microcomputer is the smallest type of computer.
In a binary system there are only two symbols.
X-ray, MRI, and ultrasound systems in hospitals are examples of analog systems.
The arithmetic/logic unit will send the results of its decisions to memory.
Digital systems require that voltage levels change between high and low.
In a serial data system, the data is transmitted along a group of conductors simultaneously.
It is possible to have an overlap between high and low levels in digital logic.
The LSB is always to the right of the MSB.
Using digital techniques of information storage is easy.
One advantage of analog circuits over digital circuits is that it's easier to store data.
Greater accuracy and precision are possible with digital techniques.
The CPU (Central Processing Unit) is composed of memory and outputs.
