Can Somebody Help Me What Is The Approximate Frequency Of This Signal In This Time Window class=

Sagot :

Answer:

The approximate frequency of the signal is 12 Hertz

Explanation:

Frequency is defined as the number of complete cycles that passes a given point in a given time

One cycle is the motion that describes one complete rotation, such that one cycle is described by the region between successive crest or peaks

Therefore, we have from the diagram;

The number of cycles in 0.75 seconds ≈ 9 cycles

The number of cycles expected to pass in one second = 9 cycles/(0.75 seconds) = 12 cycles/second = 12 Hertz

The approximate frequency of the signal, f = 12 cycles/second = 12 Hertz.
