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.

Which modulation technique is used in gsm?
GSM uses GMSK modulation scheme. GPRS also uses GMSK modulation scheme. EDGE and UMTS uses 8-PSK.
What is the modulation technique used in microwave pdh as nec equipment?
QAM... (16 QAM, 256 QAM) according to capacity
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.
In order to send more than one bit at a time during a single phase on a carrier modulation is used?
amplitude modulation is used
What modulation technique used in tv broadcasting?
AM and FM

Qam only
What is the modulation technique used in pdh as nec equipment?
QPSK
What is delta modulation?
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.

What is the difference between the AM modulation and ASK modulation?
This is hard to explain. AM means amplitude modulation, while ASK is amplitude-shift keying. AM is usually analog as it is modulated based on the strength of the signal, though you can use it to send a digital signal. ASK represents digital data as variations in the amplitude of a carrier wave. Any digital modulation technique will represent the data using a finite number of different signals. While AM is used mostly for radio and television, ASK is used for telegraph signals, transmission across telecommunications equipment, and fiber optics.

What does Base stand for in 100BaseT?
"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.
WHAT modulation technique is used for HSUPA?
Up to Rel.6 a modified QPSK is used, combining Control and Data channels on E-DCH. With Rel.7 a higher order modulation is introduced - 16QAM allowing to double the maximum theoretical speeds to 11.6 Mbps.
