🔍 Key Concepts

• Rectifier output vs. true DC voltage • What a filter (capacitor/inductor network) does in a power supply • Difference between removing ripple and providing steady DC

💭 Think About

• Think about what the voltage looks like immediately after rectification – is it perfectly flat DC or does it still vary? • Ask yourself: does the filter act directly on the rectifier’s waveform, or is its purpose better described by the end result seen by the load? • Consider whether one statement might describe the process and the other the final effect – are they really different functions or two ways of saying the same thing?

✅ Before You Answer

• Examine which choice best matches the primary, textbook definition of a power supply filter • Decide if a filter’s key role is more about the waveform shape (ripple smoothing) or the overall DC output delivered • Be sure that any answer you pick could be applied to both capacitor-input and choke-input filters in typical DC power supplies
