Radio Receivers The controlled oscillator synthesizer is sometimes preferred over the direct one because It is relatively free of spurious frequency It is a simpler piece of equipment It does not require crystal oscillator Its frequency stability is better It is relatively free of spurious frequency It is a simpler piece of equipment It does not require crystal oscillator Its frequency stability is better 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: Better linearity Fewer tuned circuits Greater limiting Much easier alignment Better linearity Fewer tuned circuits Greater limiting Much easier alignment ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers When a receiver has good blocking performance, this means that It does not suffer from double-spotting Its image frequency rejection is poor It is unaffected by AGC derived from nearby transmissions Its detector suffers from burnout It does not suffer from double-spotting Its image frequency rejection is poor It is unaffected by AGC derived from nearby transmissions Its detector suffers from burnout ANSWER DOWNLOAD EXAMIANS APP

Radio Receivers In a ratio detector 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 the linearity is worse than in phase discriminator ANSWER DOWNLOAD EXAMIANS APP
