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, the usual choice to explore the time response is through the step response to a step input, or the impulse response to a Dirac delta function input. In the frequency domain (for ex… WebA discrete time transfer function is created by specifying a nonzero ‘timebase’ dt when the system is constructed: dt = 0: continuous time system (default) dt > 0: discrete time …
