It is used for the radio control of model aircraft,boats, cars.
Single side band suppressed carrier modulation is like amplitude modulation except that one of the sidebands is suppressed or filtered out. Each sideband carries the same though opposite, information, so suppressing the one sideband allows more power to be placed into the one remaining sideband. The downside, of course, is that the demodulation process is more complex.
Phase modultion is one of the three ways of modulating or altering a signal so that it is able to carry information. The other two are amplitude and frequency modulation. Phase modulation is used in high speed modems.
Signals of different frequencies cannot interfere with each other. For example can audio waves (speech) interfere with AM or FM signals?? So when we perform modulation we just transfer the message to another amplitude/frequency/phase. Hence they will never interfere with signals which are not in the same range as them. Regards Arvind
The SL100 is a PNP medium power transistor, suitable for use up to ~100MHz. This can be used in the power amplifier stage, with the output connected to a tuning network/transformer + antenna for AM modulation. It's purpose, if used in this application, is to supply current (usually a voltage amplifier circuit will precede this one) to drive the antenna.
MOdulation DEModulation.
demodulation or detection.
modulation and demodulation
modulation and demodulation
modem
its nothing but modulation and demodulation. modulation of the message is done in transmitter side and demodulation is done at receiver side and retrieving the original message.

Function Of Modem Is Modulation And Demodulation
Function Of Modem Is Modulation And Demodulation
MODEM modulation & demodulation .......
Demodulation the opposite is Modulation And when you put them together you get MODEM Modulation/Demodulation = MODEM
Demodulation is needed with modulation becoz modulation it is converting analog to digital signal n we can't understand digital. That's why we require digital to analog converter or demodulator.
