Bandwidth refers to:

Bandwidth refers to:

• A. Number of cycles per pulse
• B. Range of frequencies in a frame
• C. Range of frequencies in a pulse
• D. Rate of pulse repetition frequency

Answer: (C)

Bandwidth is the range of frequencies contained in a signal. It reflects the spectrum the signal uses. A short, sharp pulse has many frequency components, so its bandwidth is wide; longer, smoother waves have a narrower bandwidth. So describing bandwidth as the range of frequencies in a pulse directly captures its spectral width. The other ideas—how many cycles occur in a pulse, the framing of data, or how often pulses repeat—do not define the signal’s frequency spread.
