On the periods of a periodic function
International Journal of Mathematical Education in Science and Technology, 2005It is known that any nonconstant real-valued periodic function defined on the set of all real numbers is either discontinuous at each point of its domain or has a least positive period. Using the additive semigroup consisting of non-negative periods, we generalize this result by giving a unified proof of the same conclusion when the domain of the given

On the Distribution Functions of Almost Periodic Functions
American Journal of Mathematics, 1938Introduction. While it is known 1 that every almost periodic function z (t), oo < t < + oo, has an asymptotic distribution function u, very little is known about sufficient conditions which, when imposed on z(t), insure a preassigned degree of smoothness for the function u.

The wavelet transform of periodic function and nonstationary periodic function
Applied Mathematics and Mechanics, 2002The authors present some properties of the wavelet transform of trigonometric functions, periodic functions, and a class of nonstationary periodic functions. A new reconstruction equation for these functions is introduced. By using it a better reconstructed wave shape can be obtained.

This chapter deals with periodic functions, which are functions that have a certain basic pattern of behaviour or cycle that repeats. It refers to the basic trigonometric functions: the sine and cosine, which are the most commonly used and relevant periodic functions.
