What system control determines the amount of amplification that occurs in the receiver?

• A. Gain
• B. Pulse repetition frequency
• C. Rectification
• D. Acoustic power output

Answer: (A)

Gain is the control that sets how much the receiver amplifies the incoming echoes. It boosts the strength of the detected signals after they’re received, making faint echoes more visible on the display and helping with overall image brightness and detail. This is different from pulse repetition frequency, which only changes how often pulses are sent (affecting frame rate), rectification, which is part of signal processing to prepare the signal for display, and acoustic power output, which is the transmitter’s energy sent into the tissue. In short, gain determines the receiver’s amplification of the echoed signal.
