-
- "harmonics". And yes, a square wave has only the odd ones. There are still
- an infinite number of them (for a perfect square wave).

- Perhaps if you had some curiosity in fields outside your specialty you would
- have come across the fact that there are an infinite number of positive odd
- integers, just as there are an infinite number of positive integers.
