What else can I help you with?
When several signals can be transmitted at once it is called?
When several signal transmitted simultaneously. this is called multiplexing of signals.many signal are combined into one and then they transmitted.
What is the difference between microwave and an AM signal?
The primary difference is that the microwave signal is of a much higher frequency than an AM signal, if that AM signal is speaking to AM broadcast radio. In general, AM, or amplitude modulation, is not generally used as a modulation technique on microwave frequencies because there are other ways to put a signal on a microwave carrier that allow more information to be transmitted. AM is "low frequency" RF, while FM is a bit higher on the radio frequency spectrum, and microwaves are further on up.
What wave is combined with another analog signal to produce a unique signal that gets transmitted from one node to another?
Carrier
What advantage do regenerative repeaters have when used for digital communication?
When any digital signal is transmitted over a pair of wires, it degrades in amplitude. Regenerative repeaters receives the incoming signal, extracts the clock, then regenerates the original signal as a clean digital square wave as if it was the original signal transmitted from the source. Thus the name repeater.
How can you convert the digital signal given on the speedometer in the car into radio waves which can be received some where else?
First of all digital signal cant be transmitted wirelessly. digital signal can only be transmitted through optical fibre in the form of pulses. so we have to convert digital signal to analog form with the help of DIGITAL TO ANALOG CONVERTOR ( D TO A CONVERTOR). Then this analog signal should be super imposed on carrier signal called MODULATION. modem can be used for that. then that signal can be transmitted to the air through alloted band width like cellular system with the help of transceiver. at the reciveing end we can demodulate the signal with the help of modem & can convert it back to digital form through A TO D CONVERTOR.
How is FM transmitted?
the digital signal is converted to analog signal after using by transmitted antenna
When several signals can be transmitted at once it is called?
When several signal transmitted simultaneously. this is called multiplexing of signals.many signal are combined into one and then they transmitted.
What kind of signal does a mobile phone give off?
Microwaves.
How are analog signals transmitted-?
Analog signals are transmitted as electrical waves.
Why is reflection of signal useful?
Reflection of a transmitted signal is the basic premise of radar and sonar.
Is it right that a television channel is characterized by frequency of transmitted signal?
Yes, this is a true statement. A TV channel is most often characterized by the frequency of its transmitted signal.
How is mobille phones signal transmitted?
Radio Waves
What happens to a signal when transmitted over long distances?
the signal goes out of sink due to refraction

How information is transmitted?
by analog to digital,digital to analog signal
How does interference between two radio waves affect the quality of the signal being transmitted?
Interference between two radio waves can disrupt the signal being transmitted, causing distortion or weakening of the quality of the signal received. This can result in static, noise, or even complete loss of the signal.
What a modems used for?
A modem is a modulator and demodulator device that modulates the analog carrier signal to encode the digital information and demodulates the signal to decode the transmitted information. The modem usually produces a signal that can be transmitted easily and decoded to reproduce the original data.
