In what ways can a transistor amplifier modulator be modulated?
If I remember correctly, the definition of "modulation" is a "change in amplitude or frequency".
What is the difference between microwave and an AM signal?
The primary difference is that the microwave signal is of a much higher frequency than an AM signal, if that AM signal is speaking to AM broadcast radio. In general, AM, or amplitude modulation, is not generally used as a modulation technique on microwave frequencies because there are other ways to put a signal on a microwave carrier that allow more information to be transmitted. AM is "low frequency" RF, while FM is a bit higher on the radio frequency spectrum, and microwaves are further on up.
How do amplitude modulation and frequency modulation differ?
Amplitude modulation is where a constant carrier is modulated by the signal, so that the envelope of the carrier represents the signal. Frequency modulation is where a constant carrier is modulated by the signal, so that the frequency of the carrier represents the signal. Phase modulation is where a constant carrier is modulated by the signal, so that the phase angle of the carrier represents the carrier.
Where is amplitude modulation used?
we have two types of signals namely the message signal and the carrier signal. so if the amplitude of the carrier is varied in accordance with the instantaneous value of the message signal then it is known as the amplitude modulation.if we want to transmit our message signal to long distances we need to do modulation and hence amplitude modulation is done. by amplitude modulation we generate side bands which consists of the part of the message which signal which is demodulated at the receiver to get back the original message signal we are using this amplitude modulation in radio communication. It will work in the traffic also with out disturbances but frequency modulation didn't work without disturbances.
What does true quom mean in the Verizon FIOS commercial?
The pronounced "quom" is the mnemonic for QUAM which stands for QUantitized Amplitude Modulation, which is one of many ways light waves may be modulated to carry information.
What does 'FM' stand for on the end of a radio station?
"FM" stands for "Frequency Modulation" one of the principal ways (along with Amplitude Modulation [AM], and Phase Modulation [PM]) of impressing a signal (such as audio) on a radio carrier so that it can be transmitted over the air.
What are the ways in which people communicate?
amplitude,frequency,angle modulations
How an electronic transmitters work?
A transmitter takes in a signal and modulates a carrier wave to send that signal out. A mixer takes the signal and modifies it according to the type of transmission being done. AM means amplitude modulation. The signal determines the intensity of the transmitter signal. FM means frequency modulation. The transmitters frequency is changed by the incoming signal.There are several ways of sending a signal. Side band and other methods you can read about.
How can you tell the difference between am and FM waves explain?
AM is an abbreviation for Amplitude Modulation, while FM stands for Frequency Modulation. Both are ways of transmitting information that can be decoded, usually into sound for radios. Basically, a wave has two properties that can be changed - amplitude and frequency, as you might have guessed. Amplitude describes how big a wave is. Larger amplitude sound waves are louder, and larger amplitude light waves are brighter. Frequency describes how long it takes a wave to repeat itself, and is the distance from one peak, the high point of a wave, to another peak; or from one trough, the low point of a wave, to another trough. Amplitude modulation means changing amplitude to encode information. All AM radio stations use this. It generally encodes less information than frequency modulation, producing a lower quality sound. As a consequence, AM stations tend to be talk shows. Also, the range of AM stations is much larger than that of FM stations. Frequency modulation means changing frequency to encode information. All FM radio stations use this. It usually encodes less information than AM, and can therefore produce a better quality sound. As such, FM stations are generally used to transmit music. The range of FM stations is lower than that of AM stations. The easiest way to tell the difference between AM waves and FM waves is the frequency. AM waves tend to be low frequency for radio, while FM waves tend to be much higher. You might think that FM waves would be hard to pin down, but the change in frequency is not very large, so that different stations don't interfere with each other. There is a lot more information on the subject, but this is a quick introduction.
How do you ustream?
you can use the ustream producer or the HD broadcaster in the website. Also, if your computer cannot HD broadcast, you can SD broadcast. There are many ways, but those are my main ways i ustream.
How do electromagnetic waves carry information?
The thing about electromagnetic waves that makes them useful for communication is that we know how to generate them and how to detect them. As soon as you have that ability, you're ready to move information from one place to another. After that, the only question is: How do you put the information onto the waves ? The answer is: Change something on the waves, according to a pattern that the sender and the receiver agree on. What is there about a wave that you can change ? Not much ... only the wave's amplitude and its frequency (wavelength), and that's it! Can you do anything with those ? Example: The easiest way to change the amplitude of the wave is to turn it on and off. You can use a flashlight or a radio transmitter, turn it on and off in some pattern that you've worked out. If you use both long and short flashes, you can call it "Morse Code". If all the flashes are the same length but they come at different times, you can call it "digital communication". As long as somebody else can see your flashlight or receive your radio signal, you can send them messages if they understand your patterns. After that, the sky is the limit. You can get fancy, change the amplitude by small amounts, change the frequency by large or small amounts, change them fast or slow, change them both at the same time, and work out ways to load tremendous amounts of information onto an electromagnetic wave. Once you accomplish that, you earn the right to use big fancy names for your methods, like 'Amplitude Modulation', 'Frequency Modulation', 'Phase Modulation', and a few of my favorites: 'Seven-level Partial Response Modulation', 'Quadrature Phase Shift Keying', and '256-state Quadrature Amplitude Modulation'. But all of them are just different systems for changing the amplitude and frequency of a wave in definite patterns, and it's the patterns that carry the information.
What is analog-digital hybrid modulation?
—Analog digital hybrid modulation seeks the ways to eliminate the incoherent quantization noise component in digital communication, instead of conveniently making it minimal.
