Amplitude modulation is used in a variety of applications. Even though it is not as widely used as it was in previous years in its basic format it can nevertheless still be found.Broadcast transmissions: AM is still widely used for broadcasting on the long, medium and short wave bands. It...
Quadrature amplitude modulation (QAM) is a sophisticated modulation technique used widely in modern communication systems, particularly in digital communications. QAM combines two modulation schemes—amplitude modulation (AM) and phase modulation (PM)—totransmit dataover various media, including wireless and...
1.Amplitude Modulation (AM): In this type of modulation, the amplitude (strength) of the carrier wave is varied in proportion to the information signal. 2.Frequency Modulation (FM): In frequency modulation, the frequency of the carrier wave is varied according to the information signal. ...
Amplitude Modulation (AM): Amplitude of the carrier is modulated. Frequency Modulation (FM): Frequency of the carrier is modulated. Phase Modulation (PM): Phase of the carrier is modulated. A modem is a common example/implementation of a modulation technique in which the data is modulated...
Where Vc is the instantaneous value and Vc is the maximum value of the carrier signal, fc is the frequency of the carrier signal andωc = 2π fc. AM Waveform Analysis Theamplitude modulation equationis, VAM = Vc+Vm= Vc + Vm sin ωmt ...
What is QAM (quadrature amplitude modulation)? QAM (quadrature amplitude modulation) is a method of combining two amplitudemodulation(AM) signals into a singlechannel. This approach helps double its effectivebandwidth. QAM is also used with pulse AM (PAM) in digital systems, likewirelessapplications...
