Radio Receivers A receiver has poor IF selectivity. It will therefore also have poor Diversion reception Sensitivity Blocking Double-spotting Diversion reception Sensitivity Blocking Double-spotting ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers In a ratio detector 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 the output is twice that obtainable from a similar phase discriminator stabilization against signal strength variations is provided ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The frequency generated by each decade in a direct frequency synthesizer is much higher than the frequency shown; this is done to Reduce the number of crystals required Increase the frequency stability of the synthesizer Reduce the spurious frequency problem Reduce the number of decades Reduce the number of crystals required Increase the frequency stability of the synthesizer Reduce the spurious frequency problem Reduce the number of decades 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 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 Reducing the effect of negative-peak clipping ANSWER DOWNLOAD EXAMIANS APP
