What is radio frequency receiver?
The definition of what it is, is actually in your question. It's a receiver that operates in the radio frequency spectrum. Anything that has a transmitter is said to transmit in radio frequency or `RF`. The term radio is short for radiotelegraphy, which has become generic over the years. Where does the radio frequency start? Technically, it' at 10,000 hz and higher. That's not to say that there's lower frequency transmitters (The U.S. Gov't uses 2 hz. to reach our submarines when they're under water, but that's more of an exception than the rule. The radio frequency spectrum can extend into the gigahertz range for things such as satellite communications, and as our technology advances, we could eventually see frequencies in the teraherts. So a radio frequency receiver is anything that will receive a a frequency in the radio frequency range. Hope this helps, Cubby

Why are waves of very low frequency not used for data transmission in computer networks?

What are receiving devices in computer?
As the name suggest, a receiving device receives data that is transmitted by a sending device. Your wireless router and network access points are both senders and receivers. A receive-only device is one that receives but does not transmit. An RF receiver is an example of a receive-only device. E.g., a Freeview receiver can receive digital television transmissions but it does not transmit. A receiver is obviously not a computer in the traditional sense, but it does have microprocessors, memory and is re-programmable through firmware upgrades. It's primary purpose is to decode the transmissions it receives so, by any definition of the word, it is a computer.

What do understand by frequency modulation?
Does a walkey talkey with frequency 462.55 MHz to 467.71 MHz would work in India?
Asked in Electronics Engineering
How do you reduce noise by using modulation?
In GSM why the uplink frequency is greater than downlink frequency?
Because GSM work in multiplex mode it transmit and receive at the same time and if you use the same frequency the receiver section will receive the same signal that is transmitted, that is also why the frequencies is so far apart, is to prevent second channel interference so thatswhy bothfrequencyare different.
Asked in Computer Networking, Local Area Network
What will happen when you use a straight through cable to connect your computer to the fast ethernet interface of a router?
that depends. A router network interface is the same as a computer interface, so without a cross-over cable, your computer and router will both try to send data on the same pair of wires which doesn't work. But, some routers are smart enough to sense that data is arriving on the wrong pair of wires and it will automatically swap its transmit and receive paths to make it work. fm

How did the old receiver transmit the memory of snow to Jonas?
Asked in Electronics Engineering, Radio
Limitation of radio receiver?
Radio is limited by its own design. AM & FM bands are frequency transmitted as radio waves. However since earth is round waves travels directly they do not bend. So as a rule the higher the frequency the more direct they are FM frequency is considered as line of sight transmission AM will have more range since it operates at lower frequency. At very low frequency it is possible to transmit around the earth by using the ionosphere curvature
