What term denotes the original operating frequency of the system?

• A. Fundamental frequency
• B. Half value layer
• C. Frequency
• D. Amplitude

Answer: (A)

The fundamental frequency is the base frequency the transducer is designed to emit and defines the system’s original operating frequency. It’s the frequency used to describe the transmit signal before any nonlinear tissue effects generate harmonics. Half value layer relates to how tissue attenuates sound, not the emitted frequency. A general “frequency” term doesn’t specify the base operating value, and amplitude describes the wave’s strength, not its frequency. So the term that best fits “the original operating frequency of the system” is fundamental frequency.
