Radio Receivers If the intermediate frequency is very high (indicate false statement) Tracking will be improved The selectivity will be poor Image frequency rejection is very good The local oscillator need not be extremely stable Tracking will be improved The selectivity will be poor Image frequency rejection is very good The local oscillator need not be extremely stable ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers In a ratio detector 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 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 ANSWER DOWNLOAD EXAMIANS APP
