1/t = 1/10 micro = 100 kHz.

How 35 khz?

1/t = 1/(10*10^-6) = 100,000 k.
Here, 1 khz = 1000 hz.
So 100 khz.
Here, 1 khz = 1000 hz.
So 100 khz.

According to me,
Rise Time 10 micro Sec, Fall time 10 micro Sec.
So complete cycle time is 20 micro Sec.
Frequency = 1/Time span of 1 cycle.
Frequency = 1/20 micro Sec,
Frequency = 1/20 * 10^-6,
Frequency = 50 KHz.
Rise Time 10 micro Sec, Fall time 10 micro Sec.
So complete cycle time is 20 micro Sec.
Frequency = 1/Time span of 1 cycle.
Frequency = 1/20 micro Sec,
Frequency = 1/20 * 10^-6,
Frequency = 50 KHz.

35khz is right because fall time means fall up to 50% magnitude.
So total time is 10 +10+10 = 30us.
So 1/30u = 33.33khz.
Which is approx 35khz.
So total time is 10 +10+10 = 30us.
So 1/30u = 33.33khz.
Which is approx 35khz.
