Which modulation technique is the mos fundametal modulation technique used in telecommunications?
If we discount on/off switching af a carrier (c.w.), for instance as used for the transmission of Morse, then it must be m.c.w. in which an a.m. carrier is keyed on and off.
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.
Which modulation technique is used in gsm?
GSM uses GMSK modulation scheme. GPRS also uses GMSK modulation scheme. EDGE and UMTS uses 8-PSK.
Why phase modulation is used?
Actually phase modulation was used for the color signal in all analog TV systems.Phase modulation, with some signal preprocessing, was used to indirectly get frequency modulation in many FM transmitters.Certain modems use phase amplitude modulation.etc.
What is ppm modulation?
pulse position modulation, used in many RC model aircraft controls.
