What is a RF amplifier?
A RF amplifier is a device for electrically amplifying the power of an electrical signal, typically, but not exclusively, radio frequency signals.
Why the received signal in analog communication is distorted by the channel noise than that of digital communication?
If an RF signal is AM modulated with a analogue signal any noise will add or subtract to the amplitude of the RF signal and will be present in the audio signal after detection, also will the noise add itself to the audio signal, where as in digital communication a slight variation in the amplitude of the signal is of no concern because you only work with ones and zeros, it's high or it's low
What are the principles of mixing in electronic communications?
In receivers the received RF signal is mixed with the signal of a local oscillator of a different frequency and the intermediate frequency is then amplified by the IF stages normally 3 that resonate slightly off beat to filter out all harmonics and is then detected by the detector stage where all RF is filtered down to ground and only pure audio is then amplified In receivers the received RF signal is mixed with the signal of a local oscillator of a different frequency and the intermediate frequency is then amplified by the IF stages normally 3 that resonate slightly off beat to filter out all harmonics and is then detected by the detector stage where all RF is filtered down to ground and only pure audio is then amplified
Can laser beam be used as RF signal carrier?
When modulated with a radio frequency signal, they will indeed carry information. As in fibre-optic cables. The modulation may be of the several commonly used types, amplitude, frequency, phase ... modulation.
What happens if capacitor and inductor connected in parallel with led?
Without knowing the signals driving such a circuit and the tuning of the tank in the circuit it in not possible to give an exact answer. However assuming the tank is tuned to RF the behavior of the tank and LED should be effectively independent: the tank will respond to the RF in the signal and the LED will respond to the DC in the signal. The behavior would be different if the tank was tuned to low audio frequencies.
Is an rf power amplifier useful in the home?
The answer to whether an RF power amplifier is useful for your home depends on the qualifty if your equipment. If your T.V. is getting a weak signal for example, an RF power amplifier may be useful to get a better signal.
What is error 9 on rdc634 clarion CD player?
Error 9 on that particular changer is a weak RF signal error. That means that the unit is not sending out a strong enough signal to the antenna. Error 9 on that particular changer is a weak RF signal error. That means that the unit is not sending out a strong enough signal to the antenna.
How do you fix weak a weak turn signal on a ford e350?
e350 is bad that's why
The of an antenna depends upon the frequency of the RF signal and the gain?
The size of an antenna depends upon the frequecny of the RF signal and the gain.
What is a rf scale?
A RF scale is a measurement scale used in radio frequency technology to quantify signal strength and power levels. It is typically used to determine the strength of a radio signal in decibels (dB) relative to a reference level. A higher RF scale value indicates a stronger signal, while a lower value indicates a weaker signal.
Is rf signal much more important for capturing or not?
rf is must for modulation and demodulation.
What occurs whenever a reflected RF signal combines with the main signal?
It produces a high SWR (standing wave ratio) that limits the maximum RF (radio frequency) output.
Where can one obtain an RF signal generator?
You can obtain a RF signal generator from a variety of locations. You can try your local electronics store. If they do not stock it you can try places such as Amazon or eBay.
At what speed does an RF signal travel in space and how does it compare to the speed of light?
An RF signal travels at the speed of light in space, which is approximately 299,792 kilometers per second. This means that RF signals travel at the same speed as light in a vacuum.
What is the use detector in wireless communications?
The detector detect the audio signal in the received modulated RF signal, rectify it and filter the RF to ground and pass the pure audio to the next stage
Difference between IF and RF signal?
RF signal is coming from an antenna. So it contains electromagnetic waves. But when the signal is processed using electronics circuits, the range of frequency may not be sufficient. So that RF has to be convert to some other frequency acceptable by the circuit. And IF is the intermediate frequency used for tuning & other purpose.
What is a weak signal?
It means you have weak siganl.
