Periodic and Non Periodic Functions

p {margin: 0; padding: 0;} Periodic function Any function which repeats itself at equal intervals of time. Eg : sin fancion and cosine funct. ion are periodic functions. P(t) = sino or sincert or sin 211, T F(t) = coso or coscut or COS 2K t T Note periociic function can also express as P(E) = f (E+T) Non periodic function Any function which does not dep- eat at equal intervals of time are called non periodic functi- on. Exponential function and logarithm function are not pe- riodic. y Exponential t
