Hi Peter,

I am a little confused! When you define a square waves you said that it would contain a 1000, 3000 and 5000 hz etc. sine wave. I generated the 1000 hz tome with my music editor and analyzed it with the freq. analyzer. I found the 1000, 3000, 5000 hz in the right ratio but they did not look like sign wave. In fact it look like a very good square wave. What am I missing?
