Hundreds?


No, it's infinity, but above some number of them their amplitudes go below any measurable value.

Cheers! Rich

the more there are the more of an exact square wave it is.. if you take a signal generator and put on an ociliscope and zoom righ tin youll see little bumps all over it.

Yes, hundreds. The plural form of hundred, in other words AT LEAST 2 hundred. An infinite number is consistent with "at least 2 hundred".

Yes, but in the vernacular, \'hundreds\' is considered to be, in the limit, less than a thousand. An apt comparison, using your method, might be to say that placing rovers on Mars took tens of hours.

You're absolutely correct. I was kidding around, sorry if that wasn't obvious.
