Radio Receivers If a FET is used as the first AF amplifier in a transistor receiver, this will have the effect of Reducing the effect of negative-peak clipping Reducing the effect of noise at low modulation depths Improving the selectivity of the receiver Improving the effectiveness of the AGC Reducing the effect of negative-peak clipping Reducing the effect of noise at low modulation depths Improving the selectivity of the receiver Improving the effectiveness of the AGC 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 Its frequency stability is better It does not require crystal oscillator It is a simpler piece of equipment It is relatively free of spurious frequency Its frequency stability is better It does not require crystal oscillator It is a simpler piece of equipment ANSWER DOWNLOAD EXAMIANS APP
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.
