Analog Communication CCTC Questions and Answers 2024 If the sideband power (PSB) of an AM signal is 3.3w and the total power (PT) is 10w, what is the transmission efficiency (u;)? .33 The SSB signal power at the RF stage input is -75 dBm and the power gain is 68 dB. What is the RF stage output power? -8dBm At the RF amplifier output, the carrier signal is 250 mVrms (VRF(O)), and the output impedance is 3k ohms (R). What is the rms power of the carrier signal (PRF(O)) at the RF a...
