Radio Receivers In a ratio detector 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 stabilization against signal strength variations is provided ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The controlled oscillator synthesizer is sometimes preferred over the direct one because 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 It is relatively free of spurious frequency It is a simpler piece of equipment Its frequency stability is better ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers A receiver has poor IF selectivity. It will therefore also have poor Double-spotting Blocking Diversion reception Sensitivity Double-spotting Blocking Diversion reception Sensitivity ANSWER DOWNLOAD EXAMIANS APP
