Radio Receivers Indicate the false statement in connection with communications receivers. The noise limiter cuts off the receiver’s output during a noise pulse. A product demodulator could be used for the reception of Morse code. Variable sensitivity is used to eliminate selective fading Double conversion is used to improve image rejection The noise limiter cuts off the receiver’s output during a noise pulse. A product demodulator could be used for the reception of Morse code.

Radio Receivers The image frequency of a superheterodyne receiver Is independent of the frequency to which the receiver is tuned Is due to insufficient adjacent channel rejection Is created within the receiver itself Is not rejected be the IF tuned circuits Is independent of the frequency to which the receiver is tuned Is due to insufficient adjacent channel rejection Is created within the receiver itself Is not rejected be the IF tuned circuits ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers An AM receiver uses a diode detector for demodulation. This enables it satisfactorily to receive ISB Single-sideband, suppressed-carrier Single-sideband, reduced-carrier Single-sideband, full-carrier ISB Single-sideband, suppressed-carrier Single-sideband, reduced-carrier Single-sideband, full-carrier ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The controlled oscillator synthesizer is sometimes preferred over the direct one because It is relatively free of spurious frequency It is a simpler piece of equipment Its frequency stability is better It does not require crystal oscillator It is relatively free of spurious frequency It is a simpler piece of equipment Its frequency stability is better It does not require crystal oscillator ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers When a receiver has good blocking performance, this means that Its image frequency rejection is poor Its detector suffers from burnout It does not suffer from double-spotting It is unaffected by AGC derived from nearby transmissions Its image frequency rejection is poor Its detector suffers from burnout It does not suffer from double-spotting It is unaffected by AGC derived from nearby transmissions ANSWER DOWNLOAD EXAMIANS APP
