The amplitude modulated wave, shown here, is processed (at the receiver end), successively, into the forms (a) and (b), shown alongside.The devices, used for getting the AM input wave into the forms (a) and (bv), are known, respectively, as (1) rectifier and transducer (2) rectifier and envelope detector (3) transducer and envelope detector (4) transducer and rectifier |

Answer» Correct option: (2) rectifier and envelope detector Explanation: At the receiving end, the AM intent wave is first rectified by using a rectifier. The rectified output is then processed by an envelope detector which removes its RF component and gives its envelope (the original message signal) as its output. |
