What is the frequency in Hertz of a signal that repeats 8000

What is the frequency in Hertz of a signal that repeats 80,000 times within one minute?

What is its period (the length of one complete cycle)?

Solution

Frequency can be calculated as

As it is given 80000 times
80,000 /60 = 1333.33 Hz

The period is derived as

As it is said length of one complete cycle
1 / 1333.33 Hz = 750 milli seconds
