ANS:T9.Sideband power is a linear function of the modulation index.ANS:F10.The modulation index should be greater than 1 for best efficiency.ANS:F11.Overmodulation produces "splatter".ANS:T12.Modulation index can be derived from a time-domain view of the AM signal.ANS:T13.Modulation index can be derived from a frequency-domain view of the AM signal.ANS:T14.In AM, the lower baseband frequencies are in the LSB and the higher baseband frequencies are in the USB.ANS:F15.The upper sideband contains the same information as the lower sideband.ANS:T
16.In AM, most of the power is in the sidebands.ANS:F17.In plain AM, the job of the carrier is to allow simple demodulation.ANS:T18.The upper sideband has twice the power of the lower sideband.ANS:F19.In AM, only one information signal can be sent on any given frequency.ANS:F20.It is possible to transmit stereo audio signals using AM.ANS:T21.SSBSC is derived from DSBSC.ANS:T22.SSB AM requires twice the bandwidth of plain AM.ANS:F23.SSB AM is much more efficient than plain AM.ANS:T24.To see an envelope in SSB AM, at least two modulating audio tones are required.ANS:T25.AM has inherently worse fidelity than FM.ANS:Fa.Audio Modulationc.Angle Modulationb.Amplitude Modulationd.Antenna ModulationANS:BMULTIPLE CHOICE1.AM stands for:2.The "envelope" of an AM signal is due to:3.If the audio Vasin(at) modulates the carrier Vcsin(ct), then the modulation index, m, is:4.The equation for full-carrier AM is:5.Overmodulation causes:a.distortionc.both a and bb.splatterd.none of the aboveANS:C6.The peak voltage of an AM signal goes from Emaxto Emin. The modulation index, m, is:
