Question
For an 'up' counter, which TBPRD corresponds to a switching frequency of 10kHz?
Question 2
Select one:
- a. 20,000
- b. 50,000
- c. 10,000
- d. 5,000
Solution
The TBPRD (Time-Base Period Register) value for a switching frequency of 10kHz in an 'up' counter can be calculated using the formula:
TBPRD = (System Clock Speed / Desired Switching Frequency) - 1
However, without knowing the system clock speed, it's impossible to determine the correct TBPRD value from the options provided.
If we assume a common clock speed of 200MHz (200,000,000Hz), the calculation would be:
TBPRD = (200,000,000 / 10,000) - 1 = 19,999
So, the closest answer would be 20,000 (option a). But again, this is assuming a 200MHz clock speed. The actual answer could be different if the clock speed is different.
