Radio Receivers The controlled oscillator synthesizer is sometimes preferred over the direct one because It does not require crystal oscillator It is a simpler piece of equipment Its frequency stability is better It is relatively free of spurious frequency It does not require crystal oscillator It is a simpler piece of equipment Its frequency stability is better It is relatively free of spurious frequency ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers In a ratio detector stabilization against signal strength variations is provided the circuit is the same as in a discriminator, except that the diodes are reversed the linearity is worse than in phase discriminator the output is twice that obtainable from a similar phase discriminator stabilization against signal strength variations is provided the circuit is the same as in a discriminator, except that the diodes are reversed the linearity is worse than in phase discriminator the output is twice that obtainable from a similar phase discriminator ANSWER DOWNLOAD EXAMIANS APP

Radio Receivers Show which of the following statements about the amplitude limiter is untrue: The output must be tuned Leak-type bias must be used When the input increases past the threshold of the limiting, the gain decreases to keep the output constant. The circuit is always biased in class C, by virtue of the leak-type bias.
