Frequency

Share This:

Frequency is how fast you shake the string with your hand. The faster you shake your hand, the more 'waves' you make. The number of 'waves' that happen in one second is the 'frequency' of a signal. Using our string analogy, the high points of the moving string are the maximums, and the lowest points are the minimums. The distance between one minimum and the next maximum is referred to as a 'wave'. The distance between the minimum of the first wave, and the minimum of the next wave is called the 'period'.
