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 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 The local oscillator of a broadcast receiver is tuned to a frequency higher than the incoming frequency To allow adequate frequency coverage without switching Because otherwise an intermediate frequency could not be produced To permit easier tracking To help the image frequency rejection To allow adequate frequency coverage without switching Because otherwise an intermediate frequency could not be produced To permit easier tracking To help the image frequency rejection ANSWER DOWNLOAD EXAMIANS APP
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 Its frequency stability is better It does not require crystal oscillator It is relatively free of spurious frequency It is a simpler piece of equipment Its frequency stability is better It does not require crystal oscillator ANSWER DOWNLOAD EXAMIANS APP
