Please define even and odd harmonics formulas.

What is the formula for second harmonic and so on?

As harmonics start from 2wt, 3wt, 4wt, 5wt, ..So on. As we have to determine the 1st odd harmonic so we have to determine 3wt. Now 3*(1/60us) = 50kHz.

Why 3 ?

TIME=60us
f=1/t
=16.66
3 harmonics=3*16.66
=49.98~=50KHZ'

t=60us
f=1/t=1/60us=16.66kHz
1st odd harmonic is 3*f=50KHz
