Radio Receivers A low ratio of the ac to the dc load impedance of a diode detector results in Poor AF response Diagonal clipping Negative-peak clipping Poor AGC operation Poor AF response Diagonal clipping Negative-peak clipping Poor AGC operation ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers An AM receiver uses a diode detector for demodulation. This enables it satisfactorily to receive Single-sideband, suppressed-carrier ISB Single-sideband, reduced-carrier Single-sideband, full-carrier Single-sideband, suppressed-carrier ISB Single-sideband, reduced-carrier Single-sideband, full-carrier ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The frequency generated by each decade in a direct frequency synthesizer is much higher than the frequency shown; this is done to Reduce the spurious frequency problem Increase the frequency stability of the synthesizer Reduce the number of crystals required Reduce the number of decades Reduce the spurious frequency problem Increase the frequency stability of the synthesizer Reduce the number of crystals required Reduce the number of decades 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 1650 kHz 900 kHz 750 kHz 2100 kHz 1650 kHz 900 kHz 750 kHz 2100 kHz ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The local oscillator of a broadcast receiver is tuned to a frequency higher than the incoming frequency To help the image frequency rejection Because otherwise an intermediate frequency could not be produced To permit easier tracking To allow adequate frequency coverage without switching To help the image frequency rejection Because otherwise an intermediate frequency could not be produced To permit easier tracking To allow adequate frequency coverage without switching ANSWER DOWNLOAD EXAMIANS APP
