The frequency is the reciprocal of the period. In other words, divide 1 by the period. If the period is in seconds, the frequency is in hertz.
Period = 1 / frequency = 1/272 = 0.003676 second (rounded)
The period is the reciprocal of the frequency, in this case, 1/250 second.
Its' reciprocal. 400 kilohertz.
Frequency = 1 / period = 1 / 0.807 = 1.2392 Hz (rounded)
Period = 1/frequency = 1/50,000 = 0.00002 second = 20 microseconds
The definiton of period (T) . Is T = 1/f ; Therefore if you know that the period is 2.5
A sine wave is a simple vertical line in the frequency domain because the horizontal axis of the frequency domain is frequency, and there is only one frequency, i.e. no harmonics, in a pure sine wave.
Period = reciprocal of ('1' divided by) the frequency = 1/200,000 = 0.000005 second = 5 microseconds
Neither of them has ANY bandwidth. All of the energy in a sine wave is concentratedat a single frequency, and there is no energy at any other frequency, no matter howclose.
