Digital and Analog Signal Retake

Front

What is a digital signal?

Back

A digital signal is an electric signal whose values change between two distinct values, typically represented as 0s and 1s.

Front

What is an analog signal?

Back

An analog signal is a continuous signal that represents physical measurements and can take on any value within a given range.

Front

What does it mean to encode a signal?

Back

Encoding a signal means converting information into a specific format for efficient transmission or storage, such as writing a word in Morse code.

Front

What is the first step in the communication process using signals?

Back

The first step is to encode the information.

Front

What device receives, processes, stores, and produces data?

Back

A computer.

Front

What is the correct order of steps in communication using signals?

Back

The correct order is: encode, transmit, decode.

Front

What is an example of a digital signal?

Back

An example of a digital signal is a binary code, which uses 0s and 1s to represent information.

Front

What is the difference between digital and analog signals?

Back

Digital signals have discrete values (0s and 1s), while analog signals have continuous values.

Front

What is the purpose of decoding a signal?

Back

Decoding a signal is the process of interpreting the encoded information back into a format that can be understood.

Front

What is a wave pulse in signal transmission?

Back

A wave pulse is a single disturbance that travels through a medium, representing a unit of information in signal transmission.
