研究提案的一般結構 (PART C)
Lisa Gerrard，1961年4月12日－）是澳洲女音樂家、女低音歌手、作曲家，懂得演奏揚琴、手風琴。她在1981－1996年是樂隊死亡之舞(Dead Can Dance)的成員。
A solid background in quality control, financial analysis, and industrial management at National Chiao Tung University explains Bob’s determination to become a successful manager. During graduate school, he participated in many collaborative projects that involved industrial organizations such as ITRI, AMAT and Chailease Finance. This invaluable exposure made ABC Corporation a logical choice for his first employment upon graduation, owing to its active role among global enterprises. Eager to contribute to the strengthening of ABC’s organizational culture, Bob has been preparing for several years to enter the challenging semiconductor industry. As is well known, the intensely competitive global market is driven by customers who demand the highest quality products. With this in mind, Bob believes that ABC company will provide him not only with a dynamic environment in which to apply his academic skills but also invaluable training to become an effective manager.

工程計劃建構 In high-speed optical communications, the clock and data recovery (CDR) circuit is largely responsible for recovery of the clock used to sample the data bits. The signal stream in point-to-point communication systems such as SONET is continuous; otherwise, during the idle time, some synchronization bits are transmitted to maintain the bit-level synchronization between the transmitter and the receiver. In these systems, CDR based on Phase Lock Loop (PLL) design is widely recognized as the optimal solution. PLL-based CDR has been increasingly studied to remain apace of higher data rate system requirements. Time division multiplexing (TDM) passive optical network (PON) is a promising means of resolving bottlenecks in broadband access. Among the standards specified and the most widely accepted ones include Ethernet PON and Gigabit PON standardized by IEEE and ITUT-T, respectively. In these TDM PON systems, the upstream traffic aggregating to the optical line terminal consists of bursts from various optical network units. 工程計劃問題Therefore, recovering a clock in a relatively short time to increase efficiency is problematic given that the burst length in conventional PON systems is no longer than thousands of bits. Applying the conventionally adopted PLL CDR to PON systems is problematic given its relatively long recovery time. (NOTE : Add 2-3 sentences that describe characteristics of the problem or statistics that reflect its severity) 工程計劃問題的量化 For instance, a commercially available PLL-CDR chip used in a legacy continuous optical link generally takes two thousand bits to lock its voltage controlled oscillator (VCO) to the incoming data in both phase and frequency. 工程計劃問題的中心 This long locking time appears to be intolerable for systems like PON. 工程計劃需求 Therefore, a novel CDR scheme must be developed, capable of recovering a clock efficiently to increase the pocket efficiency of PON systems.
