How the frequency and the period are defined for a periodic signal?

The frequency of a signal tells us how many times the signal repeats itself during one second. Units of frequency are in cycles per second, or Hertz (abbreviated as Hz). Therefore, a signal with a frequency of 100Hz goes through 100 cycles (periods) in one second—the period of the signal is 0.01 seconds.

How is periodic signal defined?

A periodic signal is one that repeats the sequence of values exactly after a fixed length of time, known as the period.

What is a periodic frequency?

Frequency refers to the number of occurrences of a periodic event per time and is measured in cycles/second. In this case, there are 10 cycles per 2 minutes (also known as 10 cycles per 120 seconds). So the frequency is. f =10 cycles / 120 s = 0.0833 cycles/s.

How do you find the period of a periodic signal?

Periodic Functions

x(t) = x(t + nT). The minimum value of T that satisfies x(t) = x(t + T) is called the fundamental period of the signal and we denote it as T₀. Examples of periodic signals are infinite sine and cosine waves. Examples: Given x₁(t) = cos(3t), and x₂(t) = sin(5t).
