Radio Receivers In a ratio detector the output is twice that obtainable from a similar phase discriminator the linearity is worse than in 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 output is twice that obtainable from a similar phase discriminator the linearity is worse than in phase discriminator the circuit is the same as in a discriminator, except that the diodes are reversed stabilization against signal strength variations is provided ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers If the intermediate frequency is very high (indicate false statement) The local oscillator need not be extremely stable Tracking will be improved Image frequency rejection is very good The selectivity will be poor The local oscillator need not be extremely stable Tracking will be improved Image frequency rejection is very good The selectivity will be poor ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers When a receiver has good blocking performance, this means that It is unaffected by AGC derived from nearby transmissions Its image frequency rejection is poor It does not suffer from double-spotting Its detector suffers from burnout It is unaffected by AGC derived from nearby transmissions Its image frequency rejection is poor It does not suffer from double-spotting Its detector suffers from burnout 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 The receiver cannot use a phase comparator for AFC Production of AGC is a rather complicated process The transmission is not compatible with A3E Adjacent-channel rejection is more difficult The receiver cannot use a phase comparator for AFC Production of AGC is a rather complicated process ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers In a broadcast superheterodyne receiver, the Mixer input must be tuned to the signal frequency Local oscillator frequency is normally double the IF Local oscillator operates below the signal frequency RF amplifier normally works at 455 kHz above the carrier frequency Mixer input must be tuned to the signal frequency Local oscillator frequency is normally double the IF Local oscillator operates below the signal frequency RF amplifier normally works at 455 kHz above the carrier frequency ANSWER DOWNLOAD EXAMIANS APP
