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… WitrynaThe technique is currently limited by the noise and thermal drift of the electronic components within the lock-in amplifier, limiting the maximum effective lock-in time constant to 30 sec. The technique is based on subtraction of the input signal and reference signal before using the lock-in amplifier to measure the phase. graystone quarry events and musicWitrynaSo that the next time he rapes he can go to a woman's prison?
