Bandwidth can be calculated by using the formula.
Bandwidth= 0.35/rise time.
Here rise time is 10 microseconds.
Hence;
Bandwidth= 0.35/10x10^-6,
Bandwidth= 35k Hertz.
Bandwidth= 0.35/rise time.
Here rise time is 10 microseconds.
Hence;
Bandwidth= 0.35/10x10^-6,
Bandwidth= 35k Hertz.

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.
