Frequency, f & Period, T - AC

Frequency, f & Period, T - AC

Example :

From the waferorm shown above :

a) Frequency, f = 2Hz

b) Period, T = 1/f

                       1/2

                        0.5 s (time for one cycle)

Peak value ( Amplitude) Vp :

The maximum current/voltage that can be achieved by an AC sine waveform from zero at vertical axis.

Peak-to-peak value Vpp :

That is measured from the maximum positive voltage to the maximum negative voltage ( or twice its peak value).

Example :

Peak value, Vp = 3V

Peak-to-peak value, Vpp = 3 - (-3) = 6V @

                                Vpp = 2Vp

                                        = 2 X 3V

                                        = 6V
