After a sound wave is received by the transducer and converted into electricity, the returned signal is what?

Explanation:
When the reflected sound returns, it is usually much weaker than the original transmitted pulse. The ultrasound system then uses the receiver’s gain to boost that weak electrical signal so it can be processed and displayed. In other words, the returned signal is strengthened by amplification in the receiver stage.
