Radio waves
These electromagnetic waves are used in communication.
radio waves
This type of signal can easily be affected by interference
Analogue signaso
Digital signals use these two binary numbers.
0 and 1
Which signal type is continuous
Analogue
Radio waves travel at this speed in space
Speed of light
Analogue signals are smooth and _____
Continuous
Digital signals transmit information using these two states instead of a continuous wave.
On and off states
Which signal type uses binary code
Digital signal
Radio waves can travel through this empty space where there is no air.
Vacuum
This type of signal varies smoothly and can take any value within a range.
Analogue signals
They are less affected by ——
Noise or interferences
Which signal type is better for long-distance communication
Digital
Radio waves belong to this larger family of waves
Electromagnetic spectrum
One major disadvantage of analogue signals
Signal loss,noise,inteference,etc
They are used in things like ——
computers, mobile phones, and Wi-Fi.
Which signal type is more easily affected by noise?
Analogue
This property of a radio wave determines whether it is AM or FM broadcasting
Frequency
In analogue signals, the wave changes continuously in this property.
Amplitude
signals can be recreated. True or false
True
CDs and streaming services mainly use this signal type
Digital
