Jitter is extremely important in PLL based systems. The effects of jitter range from not having any effect on system operation to rendering the system completely non-functional. Reducing Jitter and power supply is one way to help to improve the system performance. This review will concentrate on jitter and power supply in PLL building blocks. The authors introduce the WSN platform for the local tree plantation. Supporting both the assumption and research the platform offers an excellent way to use sensors technology on plants. They define the design choice of sensors with their types and Their implementation on local plants to protect them from unwanted damages. In this paper, they introduce conceptually how WSN can be implemented to protect the trees from unwanted cutting or damaging.
