Radio Receivers Indicate the false statement. The superheterodyne receiver replaced the TRF receiver because the latter suffered from Gain variation over the frequency coverage range Instability Insufficient gain and sensitivity Inadequate selectivity at high frequencies Gain variation over the frequency coverage range Instability Insufficient gain and sensitivity Inadequate selectivity at high frequencies ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers Indicate the false statement in connection with communications receivers. Double conversion is used to improve image rejection Variable sensitivity is used to eliminate selective fading The noise limiter cuts off the receiver’s output during a noise pulse. A product demodulator could be used for the reception of Morse code.
