Radio Receivers Indicate the false statement. Noting that no carrier is transmitter with J3E, we see that The receiver cannot use a phase comparator for AFC Production of AGC is a rather complicated process Adjacent-channel rejection is more difficult The transmission is not compatible with A3E The receiver cannot use a phase comparator for AFC Production of AGC is a rather complicated process Adjacent-channel rejection is more difficult The transmission is not compatible with A3E ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The frequency generated by each decade in a direct frequency synthesizer is much higher than the frequency shown; this is done to Reduce the number of crystals required Reduce the number of decades Reduce the spurious frequency problem Increase the frequency stability of the synthesizer Reduce the number of crystals required Reduce the number of decades Reduce the spurious frequency problem Increase the frequency stability of the synthesizer ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The image frequency of a superheterodyne receiver Is independent of the frequency to which the receiver is tuned Is due to insufficient adjacent channel rejection Is created within the receiver itself Is not rejected be the IF tuned circuits Is independent of the frequency to which the receiver is tuned Is due to insufficient adjacent channel rejection Is created within the receiver itself Is not rejected be the IF tuned circuits ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers Three-point tracking is achieved with Double spotting The padder capacitor Variable selectivity Double conversion Double spotting The padder capacitor Variable selectivity Double conversion ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The controlled oscillator synthesizer is sometimes preferred over the direct one because It does not require crystal oscillator It is relatively free of spurious frequency It is a simpler piece of equipment Its frequency stability is better It does not require crystal oscillator It is relatively free of spurious frequency It is a simpler piece of equipment Its frequency stability is better ANSWER DOWNLOAD EXAMIANS APP
