Webwhere, y 0 y_0 y 0 is the value of y at t=0, -k is the rate constant, t is time, k is 1 T \frac{1}{T} T 1 . Time constant is used in determining frequency responses of different parts of a signal processing system. It is used in transmitters and receivers, magnetic tapes, and digital filters. 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. The time constant is the main characteristic unit of a first-order LTI system. In the time domain, … See more First order LTI systems are characterized by the differential equation $${\displaystyle \tau {\frac {dV}{dt}}+V=f(t)}$$ where τ represents the exponential decay constant and V is a … See more Suppose the forcing function is chosen as a step input so: $${\displaystyle {\frac {dV}{dt}}+{\frac {1}{\tau }}V=f(t)=Au(t),}$$ with u(t) the Heaviside step function.
