10 kHz​

Answer 1

Answer:

100kHz

35KHz

10KHz

3.5 KHz

Explanation:

my answer is 100KHz,10KHz,3.5KHz

Answer 2

Answer:

35 kHz

Explanation:

35 kHz Is the correct answer of this question.

Given: If a pulse has a rise and fall time equal to 10 microseconds.

To find : what is the highest frequency contained in it.

Solution:

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.

The rise time is commonly calculated from 10% to 90% of the value. Fall time, on the other hand, is the time it takes for the pulse to shift from the highest to the lowest value.

The time it takes a pulse to reduce its amplitude from 90 percent to 10% of its peak value.
