To improve the robustness of the HWRNG, the HWRNG signal should be oversampled and then filtered in the digital domain.
Testing has determined that a lot of the HWRNG interference consists of aliased interference at frequencies > 12 kHz. Oversampling and filtering will remove most of that interference.
