In PM  the information is transmitted using _______ .*2 pointsChange in frequencyChange in amplitudeChange in phase of the carrierNone of the above

Sinusoidal carrier signals may be modulated with information to be communicated, by influencing:Question 2Answerthe carrier frequencythe carrier phaseboth phase and amplitude togetherthe carrier amplitude

In ________, the phase of the carrier is varied to represent two or more different signal elements. Both peak amplitude and frequency remain constant.Select one:PSKQAMASKFSK

In Frequency Modulation

Ex : For the AM waveform shown below, determine a) Peak amplitude of the upper and lower side frequencies b) Peak amplitude of the unmodulated carrier c) Peak change in the amplitude of the envelope d) Coefficient of modulation Percent modulation

In Frequency Modulation –*2 pointsAmplitude of the carrier remains sameFrequency of the carrier varies in accordance with the modulating signalThe number of side bands are infinite
