Square wave from sine waves

You can approximate a square wave using sine waves and a bit of math. Just research fourier transformation. 









Morning has broken like the first morning
Blackbird has spoken like the first bird
Praise for the singing
Praise for the morning
Praise for them springing fresh from the world

Sweet the rain's new fall, sunlit from heaven
Like the first dew fall on the first grass
Praise for the sweetness of the wet garden
Sprung in completeness where his feet pass

Mine is the sunlight
Mine is the morning
Born of the one light Eden saw play
Praise with elation, praise every morning
God's recreation of the new day

Morning has broken like the first morning
Blackbird has spoken like the first bird
Praise for the singing
Praise for the morning
Praise for them springing fresh from the world

One annotation regarding the amplitude of each wave component. You need to multiply the amplitude with 4/pi to reach the amplitude of the square wave. For the first harmonic the amplitude is 127.3 V, for the next harmonic 42.4 V, and so on.

Ok, thanks. I wont correct it cause it shows what it is ment to show, but thanks for your feedback.

I just changed the reference source to 100*pi/4, so it lines up well now.

I also brought music to EC, as EC radio 📻. Lebutch did not post any music for us in the radio,. Would have liked him to habe partcipated. Maybe i put back the radio for Lebutch, love for music, as a happy new year present 🎁.

Can music give you a false sense that everything is just fine?A fiddle can deceive you that Rome is not ablaze.Or are you a Great Pretender, believing that you're doing well.
