At a recent checkup, I was shocked: Even though I was eating foods rich in saturated fat and a seemingly more indulgent diet, my total cholesterol was down 10 points, my bad LDL cholesterol was stellar, and my good HDL was the highest it's ever been.
As the frequency of the signal to be measured increases to approach the frequency of the source frequency, measurement error increases. To improve the accuracy of the frequency measurement for higher unknown frequency, we can use this second measurement method, count number of pulses in known time.
Electromagnetic energy is measured in units of wavelength and frequency. The wavelength is the distance that a wave travels in one cycle and is measured in metres. The frequency is measured by the number of cycles per second and the unit of measurement is the Hertz (Hz). One cycle per second equals one Hertz.
