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 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 It is relatively free of spurious frequency ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers A low ratio of the ac to the dc load impedance of a diode detector results in Negative-peak clipping Diagonal clipping Poor AF response Poor AGC operation Negative-peak clipping Diagonal clipping Poor AF response Poor AGC operation 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 900 kHz 2100 kHz 1650 kHz 750 kHz 900 kHz 2100 kHz 1650 kHz ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers Three-point tracking is achieved with Double spotting Variable selectivity The padder capacitor Double conversion Double spotting Variable selectivity The padder capacitor Double conversion 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 Insufficient gain and sensitivity Instability Gain variation over the frequency coverage range Inadequate selectivity at high frequencies Insufficient gain and sensitivity Instability Gain variation over the frequency coverage range ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers A receiver has poor IF selectivity. It will therefore also have poor Sensitivity Blocking Double-spotting Diversion reception Sensitivity Blocking Double-spotting Diversion reception ANSWER DOWNLOAD EXAMIANS APP
