What is RF tracking as compared to satellites?

I'm assuming you are talking about GPS when you say "satellite." RF tracking can be directional. It takes three RF receiver stations to triangulate the position of an RF transmitter and is usually less accurate than GPS. RF is also more limited by range, so the RF tracking stations are usually required to be mobile depending on the strength of the transmission signal.

What is Double conversion receiver?

A type of superheterodyne radio using two separate mixers, each producing its own intermediate frequency. The block diagram of such a receiver is like this: RF -> M1 -> IF1 -> M2 -> IF2 -> D -> AF

What is RF scanning?

Depending on how it is used, it can have different applications. However, RF scanning is where one runs a receiver through a series of radio frequencies (RF), and tries to identify a specific frequency. It can include illegal operations, such as RF scanning wherein a transmitter is used to transmit a scan to interfere with transmitters such as petrol pumps, or scanning to locate cell or wireless telephone transmissions. Or there can be harmless applications such as simply tuning a radio manually.


How do you detect a RF transmitter148-151MHZ within 5oo meters range and locate it?

Use a scanner or other portable VHF receiver, with an external directional antenna such as a loop or Yagi.


What is the function of the RF amplifier?

rf is a single tuned amplifier . Its functions are :- 1.improves selectivity ( i.e rejection of unwanted signal) , so that it prevents heterodyning which results in interference frequency. 2. improves image frequency rejection 3. improves sensitivity ( gain of amplifier ) 4.improves coupling of receiver with antenna . 5. improves signal to noise ratio. 6. reradiation of local oscillator through receiver antenna is prevented


Wireless mice use what two technologies?

Wireless mice can use RF (Radio Frequency) or IR (Infra Red) technologies. IR requires line of sight to the mouse receiver, similar to a television remote control. RF is usually the preferred method, since it does not require line of sight. Hope that helps :)


What type of energy transfers information from a radio station to the radio?

RF stands for Radio Frequency, magnetic waves radiate out of the transmitting antenna and are picked up or recovered by the receiving antenna at the receiver.
