analog and digital waves

Front

What is an analog wave?

Back

An analog wave is a continuous signal that varies over time, representing physical quantities. Examples include sound waves and light waves.

Front

What is a digital wave?

Back

A digital wave is a discrete signal that represents data in binary form (0s and 1s). It is used in digital devices like computers and smartphones.

Front

What is noise in the context of signals?

Back

Noise refers to unwanted disturbances or variations in a signal that can affect its clarity and quality.

Front

Which type of signal is more susceptible to noise?

Back

Analog signals are more susceptible to noise and distortion compared to digital signals.

Front

Why are digital signals preferred for communication?

Back

Digital signals can be easily corrected for noise and distortion, making them more reliable for communication.

Front

What does 'sampling' mean in digital recording?

Back

Sampling is the process of measuring the amplitude of an analog signal at regular intervals to convert it into a digital signal.

Front

What is high sampling precision?

Back

High sampling precision means capturing more data points in a given time, resulting in a more accurate representation of the original signal.

Front

What is the main advantage of analog recordings?

Back

Analog recordings are often described as having a 'fuller' sound, which some people prefer over digital recordings.

Front

Can noise in digital signals be corrected?

Back

Yes, noise in digital signals can be corrected easily using various techniques.

Front

What is distortion in signals?

Back

Distortion refers to any change in the original shape or characteristics of a signal, often caused by interference or noise.
