Question
1. For an AM DSBFC wave with a peak unmodulated voltage of 10 V and a load resistance of 10 N, the given modulation index is o.5. Determine the following: (a) The carrier and sideband power (b) The total power (c) The percent power of the information (d) The power spectrum 2. For a 500 W carrier modulated to a depth of 80%, find the total power and % of P.S in each of the following form of AM. (а) Ј3Е (b) НЗЕ (c) DSB 3. If a transmitter power of 100 W is sufficient for reliable communication over a certain path using SSB, approximately what power level would be required using the H3E. 4. A filter-type SSB generator uses an ideal bandpass filter with a center frequency of 5 MHz and a bandwidth of 2.7 kHz. What frequency should be used for the carrier oscillator if the generator is to produce a LSB signal with a baseband frequency response having a lower limit of 280 Hz.
