Formula for frequency and period time

The frequency is the number of periods per second. The formula below applies to the calculation of the frequency:

\(\displaystyle f= \frac{1}{T}\)

The duration of a period is calculated using the following formula:

\(\displaystyle T= \frac{1}{f}\)

Legend

\(\displaystyle f\)

Frequency in Hz

\(\displaystyle T\)

Duration of a period in seconds
