Radio Receivers Indicate which of the following statements about the advantages of the phase discriminator over the slope detector is false: Much easier alignment Better linearity Fewer tuned circuits Greater limiting Much easier alignment Better linearity Fewer tuned circuits Greater limiting ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers An AM receiver uses a diode detector for demodulation. This enables it satisfactorily to receive ISB Single-sideband, full-carrier Single-sideband, suppressed-carrier Single-sideband, reduced-carrier ISB Single-sideband, full-carrier Single-sideband, suppressed-carrier Single-sideband, reduced-carrier ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The local oscillator of a broadcast receiver is tuned to a frequency higher than the incoming frequency Because otherwise an intermediate frequency could not be produced To help the image frequency rejection To permit easier tracking To allow adequate frequency coverage without switching Because otherwise an intermediate frequency could not be produced To help the image frequency rejection To permit easier tracking To allow adequate frequency coverage without switching ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers A receiver has poor IF selectivity. It will therefore also have poor Diversion reception Sensitivity Blocking Double-spotting Diversion reception Sensitivity Blocking Double-spotting ANSWER DOWNLOAD EXAMIANS APP
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 In a broadcast superheterodyne receiver, the Local oscillator frequency is normally double the IF RF amplifier normally works at 455 kHz above the carrier frequency Local oscillator operates below the signal frequency Mixer input must be tuned to the signal frequency Local oscillator frequency is normally double the IF RF amplifier normally works at 455 kHz above the carrier frequency Local oscillator operates below the signal frequency Mixer input must be tuned to the signal frequency ANSWER DOWNLOAD EXAMIANS APP
