Radio Receivers Indicate the false statement in connection with communications receivers. The noise limiter cuts off the receiver’s output during a noise pulse. Double conversion is used to improve image rejection Variable sensitivity is used to eliminate selective fading A product demodulator could be used for the reception of Morse code.

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 It is relatively free of spurious frequency Its frequency stability is better It is a simpler piece of equipment It does not require crystal oscillator It is relatively free of spurious frequency Its frequency stability is better ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers When a receiver has good blocking performance, this means that Its image frequency rejection is poor Its detector suffers from burnout It is unaffected by AGC derived from nearby transmissions It does not suffer from double-spotting Its image frequency rejection is poor Its detector suffers from burnout It is unaffected by AGC derived from nearby transmissions It does not suffer from double-spotting ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers If the intermediate frequency is very high (indicate false statement) 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 The local oscillator need not be extremely stable ANSWER DOWNLOAD EXAMIANS APP
