1.	What happens to the gap between THDF and THDR for higher order harmonic distortion?(a) Increases(b) Decreases(c) Remains unchanged(d) Not relatedThis question was posed to me during an interview.Origin of the question is Higher-Order Harmonic Distortion in division Large Signal Amplifiers of Electronic Devices & Circuits
Answer» The CORRECT ANSWER is (a) Increases For explanation: THDF REPRESENTS the total harmonic distortion for fundamental frequency and THDR represents the total harmonic distortion for root MEAN square. For LOWER harmonics, the gap between these two values is negligible. However, for higher order harmonics the gap increases.
