Which term corresponds to the quantity associated with the magnitude of the ripple in an AC rectifier output?

• A. Ripple amplitude
• B. Band-pass
• C. Band-reject
• D. Cutoff Frequency

Answer: (A)

The quantity that describes how big the ripple is on a rectified output is ripple amplitude. After rectification, the output isn’t perfectly steady DC; it fluctuates up and down around a mean level. The size of those fluctuations—the maximum deviation from the DC level (often the peak-to-peak swing)—defines the ripple amplitude. The other terms are about frequency response of filters: band-pass and band-reject describe which frequency ranges a filter passes or rejects, and cutoff frequency is the frequency at which the filter’s response is reduced by a defined amount. They don’t quantify the size of the ripple in the rectified output. So the term that best matches the question is ripple amplitude.
