1) A collector modulated transmitter has a supply voltage of 48 V and an average collector current of 600 mA. Explain the input power to transmitter? Explain how much the modulating signal power is required to generate 100 percent modulation?
2) An SSB generator has the 9 MHz carrier and is utilized to pass voice frequencies in the 300- to 3300-Hz range. The lower sideband is selected. What is the approximate center frequency of filter required to pass the lower sideband?
3) A 1496 IC balanced modulator has a carrier-level input of 200 mV. The amount of the suppression achieved is 60 dB. How much carrier voltage appears at the output?
