Which term refers to the component of a waveform related to its frequency content?

• A. Bandwidth
• B. Amplitude
• C. Acoustic variables
• D. Compression

Answer: (A)

Frequency content of a waveform is described by how wide a range of frequencies the signal contains; that range is called bandwidth. Bandwidth captures the spectral makeup of the signal and shows how many different frequencies contribute to the waveform. Amplitude tells you how strong the wave is in time, not which frequencies are present. Acoustic variables isn’t a standard term for this concept, and compression refers to the degree of pressure variation or a processing step, not the frequency content. In ultrasound, shorter pulses have broader bandwidth because they include a wider mix of higher and lower frequencies, while longer pulses have a narrower bandwidth.
