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.
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.

Adaptive delta modulation is a analog-to-digital and digital-to-analog conversion technique which is primarily used for voice transmission data and can be used for multiple purposes.
