THD claims of audio signal generators
My ancient Heathkit audio signal generator, which uses 3 tubes and a light
bulb in an oscillator circuit, claims to produce sine waves with a total harmonic distortion less than 0.1%. My semi-ancient Hewlett-Packard HP202B oscillator only claims to produce THD less than 1%. I would have expected the HP instrument to have considerably better performance specifications because of its much more elaborate circuit. Are we simply looking at pessimistic vs. optimistic ratings? |
