GSM uses GMSK modulation scheme. GPRS also uses GMSK modulation scheme. EDGE and UMTS uses 8-PSK.
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.
Pulse-Amplitude Modulation
In television system for video transmission AM is used and for audio transmission FM is used....
pulse position modulation, used in many RC model aircraft controls.
GSM uses GMSK modulation scheme. GPRS also uses GMSK modulation scheme. EDGE and UMTS uses 8-PSK.
Amplitude Modulation (AM) is used for the picture portion of a television transmission while Frequency Modulation (FM) is used for the audio portion.
"Base band", meaning that no modulation is used."Base band", meaning that no modulation is used."Base band", meaning that no modulation is used."Base band", meaning that no modulation is used.
It is a type of Pulse modulation as in PPM the position of pulse of carrier pulse train is varied in accordance with the modulating signal.
Adaptive delta modulation is used in audio communication systems to avoid the two drawback of delta modulation.
pulse code modulation method used a telephony.

PPM is a type of pulse modulation where messages are sent using single pulses. PWM is a type of modulation which conforms to the pulse. PAM is a type of modulation in which the information is encoded into a series of pulses.
For see the answer you want sign in but for write the answer you don't need any things.
If you speak loudly then softly you have used modulation of your voice
It is used to delay the modulation
