Digital vs. Analog Signals

Front

What is the main difference between digital and analog signals?

Back

Digital signals represent data in discrete values (0s and 1s), while analog signals represent data in continuous waves.

Front

What type of signal is more affected by noise?

Back

Analog signals are more affected by noise, which can distort the quality of the signal.

Front

How are analog signals transmitted?

Back

Analog signals are transmitted as continuous waves.

Front

What is a characteristic of digital signals?

Back

Digital signals are more reliable and less susceptible to interference compared to analog signals.

Front

Which type of signal is easier to store?

Back

Digital signals are easier to store than analog signals.

Front

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

Back

Distortion refers to the alteration of the original shape or characteristics of a signal, often due to interference.

Front

Give an example of a digital signal.

Back

An example of a digital signal is a computer's binary data (0s and 1s).

Front

Give an example of an analog signal.

Back

An example of an analog signal is a vinyl record or a radio wave.

Front

What is the impact of noise on analog signals?

Back

Noise can significantly degrade the quality of analog signals, making them less clear.

Front

What are wave pulses in digital signals?

Back

Wave pulses in digital signals represent binary data, typically as 1s and 0s.
