How do you stop a satellite signal in a temple?
Microwave Radio Frequencies (RF) does not travel through dense metals. A metal roof would block the signal. If you try to get your position on a GPS inside the temple and cannot, then the satellite signals are blocked.
What is A microwave leak detector?
A portable handheld radio receiver operating in the microwave band, that when it detects microwave RF above a certain strength it gives some form of warning signal. This warning may be audible, visual, or be shown on the face of a meter.
What section of a transmitter impresses the audio information on the radio wave?
AF modulator. Audio signals produced by the microphone get amplified enough with the power to modulate the RF carrier wave generated by a RF oscillator.
What is working of buffer in rf signal generator?
A; BUFFER is used for isolation, translation of levels and amplification if needed
What is a RF?
RF is short for Right Fielder. In the context of the category where this question was posted, RF probably refers to "radio frequency". "Radio frequency" usually refers to a rate of oscillation in the range of about 30 kHz (30,000 cycles per second) to 300 GHz (300,000,000,000 cycles per second). This is the range of frequencies of electromagnetic signals we call radio waves. Although RF usually refers to electrical rather than mechanical oscillations, mechanical oscillations in this range can also be referred to as "RF" (that use is a bit obscure though).

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.
What is a modulator along with a VCR?
Television signals are transmitted on a high frequency (or RF) carrier signal. The technique of adding the signal to the carrier signal is called modulation. This happens for all radio transmissions. A VCR that has a modulator allows the output signal to be turned into an RF signal. The signal is added to the RF signals that are fed into the VCR via the aerial feed. Although it is rarely needed today, older televisions often had no video or audio input so the VCR output could be sent to the television as RF to allow the tuner to capture and display the signal. Most VCR modulators have a control to adjust the carrier frequency to allow it to use a channel that is not use by other broadcast television signals. Modulators are used less often in recorders and players as virtually all televisions have at least one video input.

What are the differences between analog and RF circuits?
analog circuit is circuit that generates audio, sound, radio etc (waves of the natural world) RF stand for radio frequency, it is often refer to the property of signal transmission in high frequency (HF). If you say a circuit is RF, the circuit would be in the frequency range between 3kHz to 300GHz. The reason that RF circuit is special is because the performance of signals of higher frequency is different to other lower frequency AC circuits. When designing a RF circuit, RF engineers have to consider the type of wires, lengths, use of components, signal loss etc. It is because high frequency signals would take a piece of wire (longer than 1/10 of signal wavelength) as wires with many inductors and capacitors.
Can RF signal travel in air medium without antenna?
Yes. An antenna is only used to receive or send a signal. A RF signal travels throughout any air medium independently of the existence or not of an antenna. Of course you will need an antenna if you want to receive the signal (which has to have, by the way, more or less the same lenght of the wavelength of the RF signal), but the propagation of a electromagnetic wave doesn't need a physical support. You can see an example with the radiotelescopes. They receive signals which come from the outer space without any physical support. Electromagnetic waves (and RF signal is one kind of them) doesn't need any physical media to travel (they travel in vacuum too!)
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.
Where can an RF circulator be purchased?
An RF circulator is used in a microwave oven. Unless one has purchased a very expensive microwave, it would probably be more cost efficient to purchase a new one than to purchase an RF circulator.
Is rf signal much more important for capturing or not?
rf is must for modulation and demodulation.
