Radio Receivers The controlled oscillator synthesizer is sometimes preferred over the direct one because 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 It does not require crystal oscillator It is relatively free of spurious frequency It is a simpler piece of equipment 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 A receiver has poor IF selectivity. It will therefore also have poor Sensitivity Blocking Diversion reception Double-spotting Sensitivity Blocking Diversion reception Double-spotting 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
