Radio Receivers In a ratio detector the circuit is the same as in a discriminator, except that the diodes are reversed stabilization against signal strength variations is provided the output is twice that obtainable from a similar phase discriminator the linearity is worse than in phase discriminator the circuit is the same as in a discriminator, except that the diodes are reversed stabilization against signal strength variations is provided the output is twice that obtainable from a similar phase discriminator the linearity is worse than in phase discriminator ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers Indicate the false statement. The superheterodyne receiver replaced the TRF receiver because the latter suffered from Instability Insufficient gain and sensitivity Gain variation over the frequency coverage range Inadequate selectivity at high frequencies Instability Insufficient gain and sensitivity Gain variation over the frequency coverage range Inadequate selectivity at high frequencies ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers One of the main functions of the RF amplifier in a superheterodyne receiver is to Permit better adjacent-channel rejection Provide improved tracking Increase the tuning range of the receiver Improve the rejection of the image frequency Permit better adjacent-channel rejection Provide improved tracking Increase the tuning range of the receiver Improve the rejection of the image frequency ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers A low ratio of the ac to the dc load impedance of a diode detector results in Poor AGC operation Diagonal clipping Negative-peak clipping Poor AF response Poor AGC operation Diagonal clipping Negative-peak clipping Poor AF response 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 Improving the effectiveness of the AGC Improving the selectivity of the receiver Reducing the effect of noise at low modulation depths Reducing the effect of negative-peak clipping Improving the effectiveness of the AGC Improving the selectivity of the receiver Reducing the effect of noise at low modulation depths Reducing the effect of negative-peak clipping ANSWER DOWNLOAD EXAMIANS APP
