Question

Calculate timer parameters. A variety of questions are provided to help you learn how to perform all sorts of timer calculations. For a timer clocked at 10MHz, how long, in nanoseconds, will each C (count) output value hold before counting up/down on the next clock edge?

Answer 1

In a timer with a 10MHz clock frequency, each C (count) output value will hold for 100 nanoseconds before the next clock edge.

Step-by-step explanation:

To calculate the time duration that each C (count) output value will hold in a timer clocked at 10MHz, you first need to understand the relationship between the clock frequency and the time period of each clock cycle.

The frequency (f) of a clock is the number of cycles it completes in one second, and is related to the time period (T) of one cycle by the formula:

T = 1/f

For a clock frequency of 10MHz, we convert megahertz to hertz to get 10,000,000 Hz. Using the formula above:

T = 1/(10,000,000 Hz)
T = 0.1μs or T = 100 ns

Therefore, for a timer with a 10MHz clock, each C (count) output value will hold for 100 nanoseconds before counting up or down on the next clock edge.
