Frequency and Period (MA029E)

The frequency is numerically the number of cycles per second (Hz) of a periodic signal or wave and is in verse proportion with the period (s).

Formula 1

f = 1 / T

Where:

f is the frequency in (Hz)

T is the period in seconds (s)

Derivated Formulas:

Formula 2

T = 1 / f

Application Example:

Calculate the frequency of a signal with a period of 0,01 ms.

Data:

T = 0,01 x 10^-3

F = ?

Using formula 1:

F = 1/0,01 x 10^-3 = 100 x 10³ = 100 kHz

Note: when time is given in milliseconds, frequency is found in quilohertz; when time is given in microseconds, frequency is found in megahertz;
