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.
Therefore, frequency is inversely proportional to period. Unit of measuring frequency is Hertz (Hz), and âFâ is the most common symbol used in physics to denote frequency. Relation of frequency and period is given by F = 1/T (or T = 1/F). For example, period of 88MHz FM wave is T = 1/F =1/88Ã106 = 11.3x 10-9 s = 11.3ns (nanoseconds).
