Radio Receivers If the intermediate frequency is very high (indicate false statement) The selectivity will be poor The local oscillator need not be extremely stable Tracking will be improved Image frequency rejection is very good The selectivity will be poor The local oscillator need not be extremely stable Tracking will be improved Image frequency rejection is very good ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The local oscillator of a broadcast receiver is tuned to a frequency higher than the incoming frequency 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 To help the image frequency rejection Because otherwise an intermediate frequency could not be produced To permit easier tracking 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 relatively free of spurious frequency It does not require crystal oscillator It is a simpler piece of equipment Its frequency stability is better It is relatively free of spurious frequency It does not require crystal oscillator It is a simpler piece of equipment ANSWER DOWNLOAD EXAMIANS APP
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 effectiveness of the AGC Improving the selectivity of the receiver Reducing the effect of negative-peak clipping Reducing the effect of noise at low modulation depths Improving the effectiveness of the AGC Improving the selectivity of the receiver ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers Indicate the false statement in connection with communications receivers. Variable sensitivity is used to eliminate selective fading Double conversion is used to improve image rejection A product demodulator could be used for the reception of Morse code. The noise limiter cuts off the receiver’s output during a noise pulse.
