Radio Receivers The controlled oscillator synthesizer is sometimes preferred over the direct one because 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 It is a simpler piece of equipment ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers When a receiver has good blocking performance, this means that Its image frequency rejection is poor It is unaffected by AGC derived from nearby transmissions Its detector suffers from burnout It does not suffer from double-spotting Its image frequency rejection is poor It is unaffected by AGC derived from nearby transmissions Its detector suffers from burnout It does not suffer from double-spotting ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The local oscillator of a broadcast receiver is tuned to a frequency higher than the incoming frequency To allow adequate frequency coverage without switching To permit easier tracking To help the image frequency rejection Because otherwise an intermediate frequency could not be produced To allow adequate frequency coverage without switching To permit easier tracking To help the image frequency rejection Because otherwise an intermediate frequency could not be produced ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The image frequency of a superheterodyne receiver Is not rejected be the IF tuned circuits Is independent of the frequency to which the receiver is tuned Is due to insufficient adjacent channel rejection Is created within the receiver itself Is not rejected be the IF tuned circuits Is independent of the frequency to which the receiver is tuned Is due to insufficient adjacent channel rejection Is created within the receiver itself ANSWER DOWNLOAD EXAMIANS APP
