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.

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.
Difference between RF microwave?
RF means radio frequency or relativity low range of frequency microwaves however are into the top range of the spectrum or very hi frequency.

What are the applications of single tuned coupled circuits?
The resonance effect of the LC circuit has many important applications in signal processing and communications systems.The most common application of tank circuits is tuning radio transmitters and receivers. For example, when we tune a radio to a particular station, the LC circuits are set at resonance for that particular carrier frequency.A series resonant circuit provides voltage magnification.A parallel resonant circuit provides current magnification.A parallel resonant circuit can be used as load impedance in output circuits of RF amplifiers. Due to high impedance, the gain of amplifier is maximum at resonant frequency.Both parallel and series resonant circuits are used in induction heating.LC circuits behave as electronic resonators, which are a key component in many applications:AmplifiersOscillatorsFiltersTuners
What is difference between modulator and demodulator?
Modulation is used when information is available in analog form that varies the frequency and/or amplitude of a lower frequency wave, depending on the information it carries. The role of modulation is to place this information onto a carrier frequency that can be transmitted more readily and with least loss of information. There are three fundamental types of modulation - frequency modulation, amplitude modulation and phase modulation. In each of these, a carrier frequency is modulated by a lower frequency, to form a modulated carrier wave. A modulator modulates the carrier frequency, while a demodulator detects the modulation on the carrier wave and recovers the original lower frequency waveform at the destination. For many years the modulated carrier wave was converted to a radio signal. Now it is often an electrical signal which is sent down a teleohone line; the information is usually a set of pulses going between computers. When computers are connected to each other in a two-way conversation, the MOdulator and DEModulator are combined into a single device called a MODEM.
What is the difference between analog and digital transmitter?
In a analog transmitter the RF carrier have to be modulated with the analog signal either by AM or FM where in digital transmitter the carrier is simply switched on and off a off = a zero and on = a one
What RF levels are commonly considered to be an indication of sufficient analog video level at the RF input of a TV set?
0 to -5
What is inside of cell phones?
Cellular phones contain a variety of electronics circuitry. Along with the battery, there are lots of digital circuits, many of which are microprocessors or microprocessor controlled. There are a few "token" analog circuits that handle the incoming and outgoing audio. Additionally, there are a number of RF (radio frequency) circuits that handle do the transmitting and the receiving of the signals. Without getting too technical, that's the wrap.
How are gps' made?
using custom digital signal processing circuits, at least one standard microprocessor, and fancy RF receiver circuits.

Are TV RF signals analog rather than digital?
In the US and Europe they are almost all digital.
What are specialty areas in electrical engineering?
Microelectronics, digital circuits, analogue circuits, transmission lines, Radio Frequency (RF), power, high voltage, integrated circuits, computers, networking and many more.
Circuits with op-amps?
What about 'em? There's more circuits than I could even begin to describe from DC to RF. Depends on what you want to do as to what type to use and what design is needed.
How and why did Rf values differ for each solvent system?
Due to the difference in relative affinity or partition coefficient differences between the sample and the stationary phase/mobile phase
What is Rf-value Why its has no unit?
There are no units because it is simply a ratio
What has the author I J Bahl written?
I. J. Bahl has written: 'RF and Microwave Coupled-Line Circuits' 'Fundamentals of RF and microwave transistor amplifiers' -- subject(s): Radio frequency Amplifiers, Microwave amplifiers, Transistor amplifiers
Will analog boster work on didital TV?
I think you mean a (TV antenna amplifier) RF amplifier used with coax cable. The answer is YES it will work with DTV.
