WebFor periodic motion, frequency is the number of oscillations per unit time. The relationship between frequency and period is. f = 1 T. 15.1. The SI unit for frequency is the hertz (Hz) and is defined as one cycle per second: 1 Hz = 1 cycle s or 1 Hz = 1 s = 1 s −1. A cycle is one complete oscillation.
In physics and engineering, the time constant, usually denoted by the Greek letter τ (tau), is the parameter characterizing the response to a step input of a first-order, linear time-invariant (LTI) system.
