Radio Receivers Indicate which of the following statements about the advantages of the phase discriminator over the slope detector is false: Fewer tuned circuits Better linearity Greater limiting Much easier alignment Fewer tuned circuits Better linearity Greater limiting Much easier alignment ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers A superheterodyne receiver with an IF of 450 kHz is tuned to a signal at 1200 kHz. The image frequency is 750 kHz 2100 kHz 1650 kHz 900 kHz 750 kHz 2100 kHz 1650 kHz 900 kHz ANSWER DOWNLOAD EXAMIANS APP
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 a simpler piece of equipment It is relatively free of spurious frequency Its frequency stability is better It does not require crystal oscillator It is a simpler piece of equipment It is relatively free of spurious frequency ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The image frequency of a superheterodyne receiver Is not rejected be the IF tuned circuits Is due to insufficient adjacent channel rejection Is independent of the frequency to which the receiver is tuned Is created within the receiver itself Is not rejected be the IF tuned circuits Is due to insufficient adjacent channel rejection Is independent of the frequency to which the receiver is tuned Is created within the receiver itself ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers Indicate the false statement. The superheterodyne receiver replaced the TRF receiver because the latter suffered from Instability Inadequate selectivity at high frequencies Gain variation over the frequency coverage range Insufficient gain and sensitivity Instability Inadequate selectivity at high frequencies Gain variation over the frequency coverage range Insufficient gain and sensitivity ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers If the intermediate frequency is very high (indicate false statement) Image frequency rejection is very good Tracking will be improved The selectivity will be poor The local oscillator need not be extremely stable Image frequency rejection is very good Tracking will be improved The selectivity will be poor The local oscillator need not be extremely stable ANSWER DOWNLOAD EXAMIANS APP
