Which modulation technique is used in gsm?
GSM uses GMSK modulation scheme. GPRS also uses GMSK modulation scheme. EDGE and UMTS uses 8-PSK.
Which type of modulation is used in TV transmission?
In television system for video transmission AM is used and for audio transmission FM is used....
What is hybrid modulation?
—Analog digital hybrid modulation seeks the ways to eliminate the incoherent quantization noise component in digital communication, instead of conveniently making it minimal.
What is meant by multilevel inverter?
Multilevel inverters have been attracting in favor of academia as well as industry in the recent decade for high-power and medium-voltage energy control. In addition, they can synthesize switched waveforms with lower levels of harmonic distortion than an equivalently rated two-level converter.The multilevel concept is used to decrease the harmonic distortion in the output waveform without decreasing the inverter power output. This paper presents the most important topologies like diode-clamped inverter (neutral- point clamped),capacitor-clamped (flying capacitor), and cascaded multilevel with separate dc sources.This paper also presents the most relevant modulation methods developed for this family of converters: multilevel sinusoidal pulsewidth modulation, multilevel selective harmonic elimination, and space-vector modulation.Authors strongly believe that this survey article will be very much useful to the researchers for finding out the relevant references in the field of topologies and modulation strategies of multilevel inverter.The related link for this fragment of a PDF doc can be seen right below.
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.
Which modulation is used with digital data?
-- PSK -- DPSK -- 16, 32, 64, 128, and 256 QAM
What are modulation techniques in satellite communication?

How do we design binary phase shift keying modulator with detail circuit?
circuit of modulation PSK
What the compare between psk and qpsk?
PSK (Phase Shift Keying) and QPSK (Quadrature Phase Shift Keying) are both digital modulation techniques used in communication systems. The main difference is that QPSK uses four distinct phase shifts, while PSK uses two. Therefore, QPSK can transmit twice as much data as PSK in the same amount of bandwidth.

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 is the difference between PSK and QPSK?
PSK (Phase Shift Keying) is a modulation technique where the phase of the carrier signal is varied to represent digital data. QPSK (Quadrature Phase Shift Keying) is a specific type of PSK that uses four phase shifts to encode two bits per symbol. QPSK is more bandwidth-efficient compared to regular PSK because it encodes more bits per symbol.
