In the following figure is a system of two water tanks. Mass flow into the top tank at a fixed rate q0 and exits this tank through an orifice of area A1. This exit water then flows into a second tank which has an orifice of area A2 at its bottom. Each tank has constant cross section of area A, with A>>A1,A2. (a) Determine the ODE model which governs the heights z1 and z2 of water in the system. (b) Determine the equilibrium given a fixed rate q0. (c) Linearize the system model about the equilibrium. (d) Compare the step responses of the nonlinear model and linearized model by choosing reasonable system parameters. ( (b) Plot the flow v.s. pressure drop curve with the estimated c to validate your estimation

LMS滤波算法，分别对锯齿波、方波、正弦波进行了滤波，并将滤波前后的信号进行了对比，很好的恢复出了真实信号。(LMS filter algorithm. The sawtooth wave, square wave, sine wave are filtered, and the signals are contrasted before and after filtering. The real signals are all well recoveried by this algorithm.)
