Some advantages are:
- As the frequency increases, the so does the data transfer speeds.
- The gain and directivity of the transmission antenna will increase for the the same size.
- Although signals experience more attenuation at high frequency, this could be advantageous for covert purposes.

Why the linear combination of a low frequency intelligence signal and a high frequency carrier signal is not effective as a radio transmission?
to shift the frequency of information signal ,at the frequency domain to a higher frequency ...so the information can be transmitted to the receiver.
What is high frequency tuned amplifier?
High frequency amplifier is a device which is tuned by high frequency. Tuned means the overlapping of generated frequency with that amplifier.
Webex bandwidth requirements?
Transmission bandwidth depends on modulating signal frequency and carrier frequency
What are the advantages of High Voltage DC transmission over High Voltage AC transmission system?
A few, at least. There are probably more. First, since the frequency is zero, reactive losses due to cable inductance are eliminated. Next, possible health risks due to alternating magnetic fields are reduced. Also, the non-trivial problem of syncronizing two power grids is eliminated. The DC is syncronously converted back to AC at the receiving end's phase and frequency, without regard to the generating end. Another possible benefit (from my point of view at least) is that HVDC systems are, to my knowledge, almost always run underground, eliminating unsightly transmission towers and lines.
How t convert high frequency into low frequency?
To covert a high frequency to a low one, we use flip-flops.
What are the advantages of FSK?
-> frequency shift keying promotes long distance communication. ->it has high security. ->low noise ->efficiency is high. ->decoding of signal is easy.
Why FM transmission is limited to line of sight?
the high frequency, it is in VHF band.
What are the advantages frequency modulation amplitude modulation?
Frequency modulation have some advantages over amplitude modulation, FM is not sensitive to the amplitude noise, and have high efficient use of transmitted power
Disadvantage of frequency shift key?
The disadvantage of frequency shift key is it requires high bandwidth. The advantages of it are that frequency shift keying promotes long distance communication, it has high security, low noise, efficiency is high, and decoding of signal is easy.

What is mien by carrier frequency?
High range of frequency that carries the message signals in transmission of data.after receiving the signals, the detector seperate the message and carrier .
In AM transmission the frequency which is not transmitted is?
audio frequency
What are the disadvantages and advantages of parallel transmission?
One advantage for parallel transmission is the speed that the data can travel at, while one disadvantage for parallel transmission is the high cost of it
What are advantages and disadvantages of physical transmission media?
The advantages of transmission media are it is easy to terminate, cheap cost of installation, and the high installed base. The disadvantages are the noise, they cover less distance, and may suffer interference.

What does coaxial mean?
The term coaxial comes from the inner conductor and the outer shield sharing ("co-") the same axis. It is often used as a high-frequency transmission line to carry a high-frequency or broadband signal but may also be used for frequencies as low as audio frequency.
What are the advantages of wien bridge oscillator?
RC phase shift oscillator is used to generate frequency in audio range and it is a fixed audio frequency oscillator where as wien bridge oscillator is a variable audio frequency oscillator for high frequency oscillations it is better to design wide band amplifier with LC network
