On the contrary, surely? It would be almost DC if it was 1 or 2Hz.... or is my aged brain playing tricks with my radio theory?
If it were 1 or 2Ghz it still a'int nearly DC
Well, let's say we have 0.000011574 Hz. This would have been seen as DC "the entire day", and DC with reverse polarity during the night.
Now, the real philosophical question is: When (at what frequency) will AC become DC, and close to that limit isn't the AC "nearly DC" ?
I guess that depends who you are. For a
mayfly a frequency of 0.000011574 Hz would surely feel like DC as it would not alter in it's entire life-cycle.
