Tracking(locked) ABSTRACT We were assigned to build a phase locked loop frequency synthesiser. The purpose is to help students to gain experience in hardware construction‚ coordinated teamwork and project management. The design uses 74HC4046‚ a PLL integrated circuit (IC) made from CMOS technology A PLL is a closed loop frequency system that locks the phase of an output signal to an input reference signal. The term “lock” refers to a constant or zero phase difference between two signals. The signal from

TCP/IP LAN Check Point #8 Answer: C Explanation: The network address 150.50.0.0 that was originally assigned is a class B‚ so it has a default subnet mask of 255.255.0.0. Then you need to divide this network into 7 subnets and only the net work address 255.255.240.0 provides enough networks because it will provide 16 - 2 = 14 subnets (-1 for the network address and -1 for the broadcast address‚ which gives a -2 from the total of subnets). #9 Answer: C Explanation: The network address 209

Phase Change Lab Ha Min Noh Ms. D Chemistry February 6‚ 2016 Question How does time relate to the change in temperature of H2O as it changes phases from ice to water to gas? Hypothesis If the time which H2O stays on the hot plate increases‚ then the temperature of H2O will increase and the phases from ice to water to gas will change because the heat is a source of energy to change the physical states. Background Ice is a solid form of H2O and water is a liquid form of H2O. The gas form of H2O

IP Subnet Design Project Executive Summary The acronym subnet refers to sub - networking. This is the process of logically dividing an IP network into various divisions or sections within a network. Therefore‚ sub-netting is the technique and practice of dividing a network into two or more logical networks (Narten‚ Nordmark‚ Simpson & Soliman 2007). Within a subnet‚ all computers connected to it are identifiable by their almost identical IP addresses. The use of IP addresses is in

interoperability. It was common for large networks to support multiple network protocol suites‚ with many devices unable to interoperate with other devices because of a lack of common protocols. However‚ while OSI developed its networking standards‚ TCP/IP came into widespread use on multivendor networks for internetworking; while on the local network level both Ethernet and token ring gained prominence. The OSI reference model was a major advance in the teaching of network concepts. It promoted the

What is Business Architecture? (As per TOGAF definition) According to TOGAF‚ Business Architecture describes the product and/or service strategy‚ and the organizational‚ functional‚ process‚ information‚ and geographic aspects of the business environment. How is Business Architecture scoped? The way in which the business architecture is scoped depends on a number of factors. In some cases‚ the key elements of the business architecture may be done in other activities‚ such as the enterprise

Understanding Questions Directions: Answer the following questions in complete sentences. One to two sentences will not suffice. 1. Write down what your observations as you look at the ball at different positions in its orbit around your head. The ball goes thru the same phases that the moon would go through.

IP SURVEILLANCE SYSTEM An Internet protocol camera‚ or IP camera‚ is a type of digital video camera commonly employed for surveillance‚ and which unlike analog closed circuit television (CCTV) cameras can send and receive data via a computer network and the Internet. Although most cameras that do this are webcams‚ the term "IP camera" is usually applied only to those used for surveillance. There are two kinds of IP cameras: Centralized IP cameras‚ which require a central Network Video
