Radio Receivers The controlled oscillator synthesizer is sometimes preferred over the direct one because It is relatively free of spurious frequency It does not require crystal oscillator Its frequency stability is better It is a simpler piece of equipment It is relatively free of spurious frequency It does not require crystal oscillator Its frequency stability is better It is a simpler piece of equipment ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers Indicate which of the following statements about the advantages of the phase discriminator over the slope detector is false: Greater limiting Much easier alignment Fewer tuned circuits Better linearity Greater limiting Much easier alignment Fewer tuned circuits Better linearity ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers To prevent overloading of the IF amplifier in a receiver, one should use Variable selectivity Squelch Double conversion Variable sensitivity Variable selectivity Squelch Double conversion Variable sensitivity ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers Indicate the false statement. The superheterodyne receiver replaced the TRF receiver because the latter suffered from Inadequate selectivity at high frequencies Instability Insufficient gain and sensitivity Gain variation over the frequency coverage range Inadequate selectivity at high frequencies Instability Insufficient gain and sensitivity Gain variation over the frequency coverage range ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers Three-point tracking is achieved with Variable selectivity Double spotting Double conversion The padder capacitor Variable selectivity Double spotting Double conversion The padder capacitor ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers A receiver has poor IF selectivity. It will therefore also have poor Double-spotting Diversion reception Blocking Sensitivity Double-spotting Diversion reception Blocking Sensitivity ANSWER DOWNLOAD EXAMIANS APP
