analog and digital waves

Front

What is the main difference between analog and digital waves?

Back

Analog waves are continuous signals that vary in amplitude and frequency, while digital waves are discrete signals represented by binary code (0s and 1s).

Front

Why does digital information take less space to store than analog information?

Back

Digital devices only record pieces of sound waves, not full waves.

Front

Which type of signal can easily correct noise and distortion?

Back

Digital signals can easily correct noise and distortion.

Front

What is an advantage of digital waves over analog waves?

Back

Digital waves can be perfectly duplicated.

Front

What is the string of 1s and 0s that control a computer called?

Back

Binary code.

Front

How do analog waves represent information?

Back

Analog waves represent information through continuous variations in amplitude and frequency.

Front

What is one disadvantage of analog waves?

Back

Analog waves are more susceptible to noise and distortion.

Front

What does it mean for a signal to be 'discrete'?

Back

A discrete signal is made up of distinct values or states, such as the 1s and 0s in digital signals.

Front

Can digital signals be easily manipulated?

Back

Yes, digital signals can be easily manipulated and processed using computers.

Front

What is an example of an analog device?

Back

A vinyl record player is an example of an analog device.
