Radio Receivers The image frequency of a superheterodyne receiver Is created within the receiver itself Is due to insufficient adjacent channel rejection Is not rejected be the IF tuned circuits Is independent of the frequency to which the receiver is tuned Is created within the receiver itself Is due to insufficient adjacent channel rejection Is not rejected be the IF tuned circuits Is independent of the frequency to which the receiver is tuned ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers An AM receiver uses a diode detector for demodulation. This enables it satisfactorily to receive Single-sideband, reduced-carrier Single-sideband, full-carrier ISB Single-sideband, suppressed-carrier Single-sideband, reduced-carrier Single-sideband, full-carrier ISB Single-sideband, suppressed-carrier ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers To prevent overloading of the IF amplifier in a receiver, one should use Variable selectivity Double conversion Squelch Variable sensitivity Variable selectivity Double conversion Squelch Variable sensitivity ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers If the intermediate frequency is very high (indicate false statement) Image frequency rejection is very good Tracking will be improved The local oscillator need not be extremely stable The selectivity will be poor Image frequency rejection is very good Tracking will be improved The local oscillator need not be extremely stable The selectivity will be poor ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The controlled oscillator synthesizer is sometimes preferred over the direct one because It is a simpler piece of equipment It does not require crystal oscillator Its frequency stability is better It is relatively free of spurious frequency It is a simpler piece of equipment It does not require crystal oscillator Its frequency stability is better It is relatively free of spurious frequency ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers Indicate the false statement. Noting that no carrier is transmitter with J3E, we see that The transmission is not compatible with A3E Adjacent-channel rejection is more difficult Production of AGC is a rather complicated process The receiver cannot use a phase comparator for AFC The transmission is not compatible with A3E Adjacent-channel rejection is more difficult Production of AGC is a rather complicated process The receiver cannot use a phase comparator for AFC ANSWER DOWNLOAD EXAMIANS APP
