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.
Frequency Conversion. Frequency is defined as the measure of the number of occurrences of a repeating event per unit time. To calculate the frequency, the number of occurrences of the event within a fixed time interval are counted and then it's divided by the length of the time interval. Ex: 1 Hz means that an event repeats once per second, 2 Hz is twice per second. Frequency calculation formula is: Frequency = 1 / Time.
