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 decades Reduce the number of crystals required Reduce the spurious frequency problem Increase the frequency stability of the synthesizer Reduce the number of decades Reduce the number of crystals required Reduce the spurious frequency problem Increase the frequency stability of the synthesizer ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers Indicate which of the following statements about the advantages of the phase discriminator over the slope detector is false: Much easier alignment Greater limiting Better linearity Fewer tuned circuits Much easier alignment Greater limiting Better linearity Fewer tuned circuits 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 a simpler piece of equipment It is relatively free of spurious frequency It does not require crystal oscillator Its frequency stability is better It is a simpler piece of equipment It is relatively free of spurious frequency It does not require crystal oscillator 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 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 ANSWER DOWNLOAD EXAMIANS APP
