  • Abstract: Industry standard for the control of switch mode power supply (SMPS) systems has been analog control. Now with the advent of high speed, lower cost digital signal processing (DSP) ICs, digital control there has been an increased interest in digital control of SMPS. The Power Electronics & Power Quality Laboratory of Texas A&M University is currently exploring several implementation aspects of digital control of power factor correction (PFC) stage of SMPS. Two low cost digital controllers: TMS320LF2407 and ST52x420 are evaluated for implementing PFC function.

  • Many measures, functions and protocols in digital mobile radio networks are based on the properties of the radio channel and its speci®c qualities in contrast to information transmission through guided media. For the understanding of digital mobile radio networks it is therefore absolutely necessary to know a few related basic principles. For this reason, the most important fundamentals of the radio channel and of cellular and transmission technology will be presented and brie¯y explained in the following. For a more detailed treatment, see the extensive literature [4,42,50,64]. ...

  • Your network switching equipment currently includes a 4006 Core switch and a 2900XL access switch. Your network is segmented into four functional VLANs for better network management. VLANs include “Accounting”, “Marketing” and “Engineering” for the users and “default” used for the native VLAN network management. After deciding on your subnet ranges and VTP information, illustrated below, your next step is to implement Inter-VLAN routing. Inter-VLAN routing will allow individuals and servers on your Virtual LANs to exchange information.

  • Bridges and switches are both layer-2 devices, functioning at the data link layer of the OSI Reference Model. Even though they are both layer-2 devices and have many similarities between them, they also have many differences. With advancements in hardware and technology, switches perform faster and have many more features. However, the basic functions of these two devices are the same. This chapter covers the functions of bridges and switches, the Spanning Tree Protocol (STP), and basic switch configuration tasks on Cisco’s Catalyst 1900 and 2950....

  • GSM was conceived in accordance with the guidelines of ISDN. Therefore, a reference con®guration is also de®ned for GSM systems, similar to the one used in ISDN systems. Using the reference con®guration, one gets an impression of the range of services and the kinds of interfaces to be provided by mobile stations. Furthermore, the reference con®guration indicates at which interface which protocols or functions terminate and where adaptation functions may have to be provided. The GSM reference con®guration comprises the functional blocks of a mobile station (Figure 9.
