You need a high powered amplifier.

The radio uses a transducer called an aerial to convert the radiowaves to current in a conductor, after low noise amplification and filtering to reject most of the other radiowaves that the transducer has converted, the short-term changes in the current are interpreted as a wanted modulation of the radiowave.

C. Intensify is to abate.\n\nto make worse is to lessen the problem.

A good example is when you input a pure sinusoidal signal to an amplifier which is called a "single tone" distortion test. As the amplifier becomes more and more over driven by increasing the amplitude of the sinewave, you start to see distortion occurring in the shape of the sinewave. If it was an audio frequency, you'd eventually be able to hear the harmonic distortion increase. Harmonics are multiples of the pure input sinewave frequency, like 2, 3, 4, 5.... etc kilohertz (kHz) if the input is a 1 kHz sinewave. Finally, when you over drive the amplifier into complete saturation, the output will be a square wave that in theory contains an infinite number of harmonics as described by the "Fourier Series" mathematical summation of the fundamental and harmonic frequencies contained in a periodic square wave signal.\nAdditional non-harmonic distortion frequencies can be generated by over driving an amplifier if you have two sinuoidal input frequencies and is called a "two-tone" distortion test.

A laser is composed of an active laser medium, or gain medium, and a resonant optical cavity. The gain medium transfers external energy into the laser beam. It is a material of controlled purity, size, and shape, which amplifies the beam by the quantum mechanical process of stimulated emission, discovered by Albert Einstein while researching the photoelectric effect. The gain medium is energized, or pumped, by an external energy source. Examples of pump sources include electricity and light, for example from a flash lamp or from another laser. The pump energy is absorbed by the laser medium, putting some of its particles into high-energy ("excited") quantum states. When the number of particles in one excited state exceeds the number of particles in some lower-energy state, population inversion is achieved. In this condition, an optical beam passing through the medium produces more stimulated emission than the stimulated absorption, so the beam is amplified. An excited laser medium can also function as an optical amplifier.

It amplifies one side or the other causing the swing to be even greater.

The amplification occurs when the wave travels from the air medium (outer ear) to the liquid medium (inner ear).  The bones that are attached to the ear drum actually amplify the wave.  This is acheived by a lever action of the bone.  The sound wave vibrates the bone (I can't remember which bone, there are 3).  The bone is secured at a fulcrum so that one end causes the other to vibrate more forcefully.  Here's an example.  If you hold a pencil about an inch from the eraser.  Then flick the eraser end up and down.  Notice how the other end (if it is a long pencil of course) moves up and down more than the eraser end.  This is the exact same mechanism your ear uses to amplify the signal.

None really - thats why digital signalling has taken over, now we have the technology. A analogue signal attenuates over distance and if you amplify it you also amplify the noise and interference. Digital signals also attenuate but can be repeated, which leaves the unwanted part of the signal behind.

It goes little something like this:\n\nEfficacy - Power or capacity to produce a desired effect; effectiveness.

no its not amplified...........\n\nits just the way as u see things

It essentially means "given more praise than deserved." When someone really pumps something up, and upon experiencing it (or whatever) you are "underwhelmed" or disappointed. \n\nFor example - I often find that most big Hollywood 'blockbuster' movies are massively overrated.

A laser (from the acronym Light Amplification by Stimulated Emission of Radiation) is an optical source that emits photons in a coherent beam. The verb to lase means "to produce coherent light" or possibly "to apply laser light to", and is a back-formation of the term laser.\n\nLaser light is typically near-monochromatic, i.e. consisting of a single wavelength or color, and emitted in a narrow beam. This is in contrast to common light sources, such as the incandescent light bulb, which emit incoherent photons in almost all directions, usually over a wide spectrum of wavelengths.\n\nLaser action is explained by the theories of quantum mechanics and thermodynamics. Many materials have been found to have the required characteristics to form the laser gain medium needed to power a laser, and these have led to the invention of many types of lasers with different characteristics suitable for different applications.\n\nThe laser was proposed as a variation of the maser principle in the late 1950s, and the first laser was demonstrated in 1960. Since that time, laser manufacturing has become a multi-billion dollar industry, and the laser has found applications in fields including science, industry, medicine, and consumer electronics.

You probably want alpha, the common base current gain. In general, current gain is designated "beta," "alpha," or "gamma," for transistors connected in the common emitter, common base, or common collector configurations, respectively.  Beta = di(c)/di(b), the rate of change of collector current with respect to change in base current.  Alpha =di(c)/di(e), rate of change of collector current with respect to change in emitter current.  Gamma = di(e)/di(b), rate of change of emitter current with respect to change in base current.  Also, alpha = (beta)/(beta - 1), beta = (alpha)/(alpha - 1), and gamma = beta + 1.  For a detailed explanation, check out : http://www.tpub.com/neets/book7/25f.htm\n\nAnother possible answer: "amplification factor" for any amplifier circuit, regardless of configuration, or whether it uses tubes, BJTs, FETs, etc, refers to its voltage gain, dv(out)/dv(in), the change in output voltage with respect to a change in input voltage.

The voice / music is modulated (FM: Frequency or AM: Amplitude), once the signal is modulated it is amplified and trasmitted to an Antenna that amplifies the signal again in order to reach your radio device.\nYour radio take that signal from the air (it has been atenuated while travling in the air), de-modulate the signal and extract the voice/music to be amplified so you can listen what is being played at radio station...\nThis is the basics, but there are many things involved in a broadcast process...
