A: A carrier carry information by modulation either Amplitude or Frequency modulation. Therefore AM and FM RADIO M stand for modulation
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.
GSM uses GMSK modulation scheme. GPRS also uses GMSK modulation scheme. EDGE and UMTS uses 8-PSK.
QAM... (16 QAM, 256 QAM) according to capacity
Explain with diagram the technique Pulse-width modulation?
The modulation techniques for video signals include the utilization of the amplitude modulation technique. The amplitude of the carrier wave is made proportional to the video signal voltage. It also utilizes frequency modulation technique.
It uses GFSK (Gaussian Frequency Shift Keying) modulation technique.
