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

Radio Receivers If the intermediate frequency is very high (indicate false statement) Image frequency rejection is very good Tracking will be improved The local oscillator need not be extremely stable The selectivity will be poor Image frequency rejection is very good Tracking will be improved The local oscillator need not be extremely stable The selectivity will be poor ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The controlled oscillator synthesizer is sometimes preferred over the direct one because Its frequency stability is better It is a simpler piece of equipment It does not require crystal oscillator It is relatively free of spurious frequency Its frequency stability is better It is a simpler piece of equipment It does not require crystal oscillator It is relatively free of spurious frequency 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 Single-sideband, full-carrier Single-sideband, reduced-carrier ISB Single-sideband, suppressed-carrier Single-sideband, full-carrier Single-sideband, reduced-carrier ISB ANSWER DOWNLOAD EXAMIANS APP
