Radio Receivers Indicate which of the following statements about the advantages of the phase discriminator over the slope detector is false: Fewer tuned circuits Better linearity Much easier alignment Greater limiting Fewer tuned circuits Better linearity Much easier alignment Greater limiting ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers To prevent overloading of the IF amplifier in a receiver, one should use Variable selectivity Double conversion Variable sensitivity Squelch Variable selectivity Double conversion Variable sensitivity Squelch ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers Indicate the false statement. The superheterodyne receiver replaced the TRF receiver because the latter suffered from Insufficient gain and sensitivity Inadequate selectivity at high frequencies Gain variation over the frequency coverage range Instability Insufficient gain and sensitivity Inadequate selectivity at high frequencies Gain variation over the frequency coverage range Instability ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers In a ratio detector the output is twice that obtainable from a similar phase discriminator stabilization against signal strength variations is provided the linearity is worse than in phase discriminator the circuit is the same as in a discriminator, except that the diodes are reversed the output is twice that obtainable from a similar phase discriminator stabilization against signal strength variations is provided the linearity is worse than in phase discriminator the circuit is the same as in a discriminator, except that the diodes are reversed ANSWER DOWNLOAD EXAMIANS APP
