Question

Если период с погрешностью равен 3.6+-0.1 миллисекунды, чему равна погрешность частоты?

Answer 1

Ответ: центральное значение частоты 1/0,0036=277,7778 Гц, верхнее значение 1/0,0035=285,714 Гц, нижнее значение 1/0,0037=270,27 Гц. В итоге имеем 277,778+/- 7,5 Гц.

Answer 2

Calculating Frequency Error

To calculate the frequency error, we can use the formula:

Frequency Error = (1 / Period) * Period Error

Where: - Period is the period of the signal - Period Error is the error in the period measurement

Given that the period with an error is 3.6 ± 0.1 milliseconds, we can calculate the frequency error using the formula above.

The period is 3.6 milliseconds, and the error in the period measurement is ± 0.1 milliseconds.

Using the formula, the frequency error can be calculated as follows:

Frequency Error = (1 / 3.6) * 0.1

Frequency Error = 0.0278 Hz

Therefore, the frequency error is 0.0278 Hz.
