Time left 00:00
10 Questions

1. What does AGC stand for?
2. A carrier of peak voltage 15 V is used to transmit a message signal. If the modulation index is 70%, then what will be the peak voltage of the modulating signal?
3. How can the noise be reduced in AM signal?
4. Why is AM used for broadcasting in the communication systems?
5. Identify the type of modulation where the frequency of the modulated wave is equal to that of the carrier wave.
6. ‘X’ for an AM is the ratio of change in amplitude of the carrier wave to the amplitude of the original carrier wave. Identify ‘X’.
7. Of the following which is the preferred modulation scheme for digital communication?
8. Suggest a possible communication channel for the transmission of a message signal that has a bandwidth of 200kHz.
9. PAM stands for pulse attenuation modulation.
10. Identify the type of modulation where the modulating wave is superimposed on a high-frequency carrier wave.
