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

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

Why 3 ?

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.

What is the formula for second harmonic and so on?

Please define even and odd harmonics formulas.

Just multiply with the frequency with 2nd 3rd 4th.
With frequency ex if ask 2 odd harmonic means take normal frequent and multiply= F * 2.
With frequency ex if ask 2 odd harmonic means take normal frequent and multiply= F * 2.
