Measuring a waveform

 

 


The Frequency in Hertz (Hz) of a waveform is equal to, the number of cycles of the wave that pass a fixed point in one second of time, or the number of cycles per second (C/S).

                   1                               1
           Hz = --------       also      Cycles = ----
                 Cycles                            Hz

The Wavelength is measured in metres (M), when the velocity of the wave in metres per second (M/S), is divided by the frequency of the wave in Hertz (Hz). In mathematical formula, Wavelength is given the Greek letter "lambda" (l). The velocity of radiowaves is taken to be the speed of light at 300 million metres per second (M/S).

                           also

                   M/S = Hz * wavelength

                           also

                             M/S
                    Hz = -----------

The root mean square (RMS) value of an alternating current power supply, is that value which is equivalent in heating effect to that of a direct current supply of the same value. The R.M.S. value is used to define an alternating voltage.
The root mean square of a sine wave is 0.707, so the R.M.S. value of a sine wave is 0.707 times the waves' peak value.
