Yes @Ruio.
6*(10^-6) , change 60us in hz.
f = 1/t=1/(60*10^-6) = (10^5)/6.
Then you will get 16666.66 Hz = 16.66 KHZ.
Now, For 1st odd harmonic = (3 * 16.66)KHZ = 50KHZ.
6*(10^-6) , change 60us in hz.
f = 1/t=1/(60*10^-6) = (10^5)/6.
Then you will get 16666.66 Hz = 16.66 KHZ.
Now, For 1st odd harmonic = (3 * 16.66)KHZ = 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'.

If they ask 1st harmonic means you have to multiply f * 2 since harmonic starts from 2, 3, 4. If they mention odd or even then you have to take which is odd and even and multiply it.

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.

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.
