UNIT TEST
1. IF the amplitude of a sine-wave message signal is increased with respect to the carrier amplitude in an AM signal, the modulation index c. will increase
2. The names intelligence, information, audio, and modulating signal all refer to a. RF waveform
3. The modulation index of an AM signal can be determined accurately d. both with measurements of the AM waveform and using the trapezoidal method
4. If the difference △ between carrier and sideband power in an AM signal is known, and Pc equal 10kW c. the transmission efficiency can be determined
5. Spurious sideband frequencies occur in commercial AM when a. the extra lobes caused by overmodulation are clipped
6. Measurements of an AM waveform show that A equal 1.5V and B equal 1V The percentage modulation is c. equal to 20%
7. Power measurements of an AM signal indicate that sideband power is 6dB less than carrier power. This indicates b. that the modulation index equals 1
