| As shown in the illustrated block diagram for a digitized echo sounding system, what statement is true concerning the function of the transducer? |
| A) The transducer converts radio frequency (RF) electromagnetic energy to acoustic energy while receiving and converts the reflected acoustic energy back into RF electromagnetic energy while transmitting. |
| B) The transducer converts radio frequency (RF) electromagnetic energy to acoustic energy while transmitting and converts the reflected acoustic energy back into RF electromagnetic energy while receiving. |
| C) The transducer converts audio frequency (AF) electromagnetic energy to acoustic energy while receiving and converts the reflected acoustic energy back into AF electromagnetic energy while transmitting. |
| D) The transducer converts audio frequency (AF) electromagnetic energy to acoustic energy while transmitting and converts the reflected acoustic energy back into AF electromagnetic energy while receiving. |
