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.
In the computer world, frequency is often used to measure processing speed. For example, clock speed, measures how many cycles a processor can complete in one second. If a computer has a 3.2GHz processor, it can can complete 3,200,000,000 cycles per second.requency can be used to measure the rate of waves, such as sound waves, radio waves, and light waves. Audible sound waves have a frequency of roughly 20 Hz to 20,000 Hz (20 kilohertz). Therefore, the sounds you hear have waves that occur anywhere from 20 to 20,000 times per second.
