👉 Quasiperiodic is a mathematical concept in mathematics and physics that refers to periodic phenomena where the amplitude of oscillations varies over time, but does not repeat itself. The term comes from the Greek words "quasi" meaning "particular," and "peridacthenes" meaning "periodic." This means that the frequency and period of a periodic function are different for each instance of the function. For example, if you have a sine wave with a frequency of 5 Hz
