As we know, the energy needed for sensors should be electrical. So the rst step before start to work is to convert environmental energy to electrical one. Inside the node there are dierent components for sensing the area, collecting data and processing the data. So the main dierent part of this kind of nodes, in compare of WSN nodes, is the power part. Once the stored energy reach to a certain amount, the power supply for micro controller and transceiver will start to work. They will continue to work until they have energy, as soon as the energy nish, they stops and energy storage device start to work to save energy again. The other fact should be consider about EH-WSN node is that the available energy can change in dierent nodes. So every node has its own harvesting rate.

Zero-order-hold Intended for a senior-level course on the analysis and design of digital control systems, the text is also useful for graduate students and practicing engineers who are learning state-space design techniques.

说明：  设计滤波器：设定10个零点，计算出多项式系数，作为滤波器系数； 取出绝对值较大的一半零点，重新设计滤波器；用剩下的绝对值较小的一半零点，重新设计滤波器。(Design a filter: Set of 10 zeros, calculate the polynomial coefficients as filter coefficients remove the larger half of the absolute value of zero, re-design filter with the remaining half of the smaller absolute zero, re-design filter.)
