1.	Overmodulation results in ________________(a) Distortion(b) Weakens signal(c) Strengthens the signal(d) provides immunity to noiseI got this question in final exam.Asked question is from Power Relations in AM Waves in portion Amplitude Modulation of Analog Communications
Answer» Correct choice is (a) Distortion Easiest EXPLANATION: When INSTANTANEOUS LEVEL of modulating signal exceeds the value necessary to provide 100% modulation, the signal is said to over-modulated. In other WORDS, when modulation INDEX is greater than 1, it results in Overmodulation. Thus, Overmodulation results in distortion of the modulating signal.
