First, we need to calculate the timer period using the formula:
Timer period = (TIM7_ARR + 1) * (TIM7_PSC + 1) / Timer clock frequency
Plugging in the values:
Timer period = (453 + 1) * (7 + 1) / 80,000,000
Timer period = 3648 / 80,000,000
Timer period ≈ 0.0000456 seconds
Now, to determine the signal acquisition time required to collect 1000 samples, we calculate the total time it will take:
Total time = Timer period * Number of samples
Total time = 0.0000456 * 1000
Total time = 0.0456 seconds
Therefore, the signal acquisition time required to collect 1000 samples is approximately 0.0456 seconds.
