Radio Receivers In a ratio detector the circuit is the same as in a discriminator, except that the diodes are reversed stabilization against signal strength variations is provided the linearity is worse than in phase discriminator the output is twice that obtainable from a similar phase discriminator the circuit is the same as in a discriminator, except that the diodes are reversed stabilization against signal strength variations is provided the linearity is worse than in phase discriminator the output is twice that obtainable from a similar phase discriminator ANSWER DOWNLOAD EXAMIANS APP

Radio Receivers One of the main functions of the RF amplifier in a superheterodyne receiver is to Permit better adjacent-channel rejection Improve the rejection of the image frequency Increase the tuning range of the receiver Provide improved tracking Permit better adjacent-channel rejection Improve the rejection of the image frequency Increase the tuning range of the receiver Provide improved tracking 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 Increase the frequency stability of the synthesizer Reduce the number of crystals required Reduce the spurious frequency problem Reduce the number of decades Increase the frequency stability of the synthesizer Reduce the number of crystals required Reduce the spurious frequency problem Reduce the number of decades ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers Indicate which of the following statements about the advantages of the phase discriminator over the slope detector is false: Greater limiting Much easier alignment Better linearity Fewer tuned circuits Greater limiting Much easier alignment Better linearity Fewer tuned circuits ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers Indicate the false statement. Noting that no carrier is transmitter with J3E, we see that 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 The receiver cannot use a phase comparator for AFC ANSWER DOWNLOAD EXAMIANS APP
