Wave Communication

Front

What is wave communication?

Back

Wave communication refers to the transmission of information using waves, such as sound waves or electromagnetic waves, to convey data over distances.

What is an analog-to-digital converter?

Back

An analog-to-digital converter (ADC) is a device that converts analog signals (continuous signals) into digital signals (discrete values) for processing and storage.

Front

How is digital data stored?

Back

Digital data is stored as a series of ones and zeros, representing binary data.

Front

What is the main difference between analog and digital data?

Back

Digital data can be stored for a longer period of time and is less susceptible to noise compared to analog data.

Front

What is noise in wave communication?

Back

Noise refers to any unwanted signal that distorts or reshapes the original wave, affecting the quality of the transmitted information.

Front

Why is digital technology preferred in music studios?

Back

Digital technology is preferred because it can store information more reliably and produce higher quality recordings than analog technology.

Front

What type of waves do remote controls use to communicate with televisions?

Back

Remote controls use electromagnetic waves to send signals to televisions.

Front

What is the advantage of digital signals over analog signals?

Back

Digital signals are less affected by noise and can maintain their quality over longer distances.

Front

What does it mean for data to be in binary form?

Back

Binary form means that data is represented using only two states: 0 (off) and 1 (on), which are the basic units of digital information.

Front

How does noise affect analog waves compared to digital waves?

Back

Noise is less of a problem for digital waves than for analog waves, as digital signals can be processed to remove distortions.
