A.
For efficiency measurements with filter-free Class-D, RL should be an inductive load like a speaker.
Figure 34. Audio Measurement Systems
The device uses a modulation scheme that does not require an output filter for operation, but they do sometimes
require an RC low-pass filter when making measurements. This is because some analyzer inputs cannot
accurately process the rapidly changing square-wave output and therefore record an extremely high level of
distortion. The RC low-pass measurement filter is used to remove the modulated waveforms so the analyzer can
measure the output sine wave.
