Engineer Project and Seminar: VOICE SWITCHING IN CELLULAR NETWORKS :How Does it Work?
http://seminarengineer.blogspot.com/2011/08/voice-switching-in-cellular-networks_4869.html
Engineer Project and Seminar. Tuesday, August 23, 2011. VOICE SWITCHING IN CELLULAR NETWORKS :How Does it Work? In the following explanation, a cellular telephone or any other device that can connect to a cellular radio network will be referred to as a mobile station. This is in keeping with the literature on the subject. Mobile station (MS): A device used to communicate over the cellular network. Base station controller (BSC): Controls communication between a group of BSTs and a single MSC. VOICE SWITCH...

http://seminarengineer.blogspot.com/2011/08/microwave-bandpass-filter-combline.html
Engineer Project and Seminar. Saturday, August 27, 2011. MICROWAVE BANDPASS FILTER :COMBLINE FILTER. The resonators in this type of filter consist of quasi transverse electromagnetic(TEM)-mode transmission lines that are short-circuited at one end and have a lumped capacitance C○ between the other end of each resonator line element and ground. Microwave network parameters :. Where Vr and Vi are –ve and ve voltage traveling waves i.e. reflected and incident wave respectively and γ. Z01)½ ( z01)½. B1= - - ...

Engineer Project and Seminar. Saturday, August 27, 2011. MICROWAVE BANDPASS FILTER : filter Types. Filter is an electrical network that can transmit signals within a specified frequency range . This frequency range is called pass band and other frequency band where the signal are suppressed is called stop band .The frequency that separates the pass and stop band is known as cut off frequency . TYPES OF FILTER :. Filters are of four types . These are as follows -. 3 Band pass filter :. Touch Screen Techno...

Engineer Project and Seminar: Touch Screen CONSTRUCTION
http://seminarengineer.blogspot.com/2011/03/touch-screen-construction.html
Engineer Project and Seminar. Sunday, March 13, 2011. There are several principal ways to build a touchscreen. The key goals are to recognize one or more fingers touching a display, to interpret the command that this represents, and to communicate the command to the appropriate application. In the most popular techniques, the capacitive or resistive approach, there are typically four layers:. 1 Top polyester layer coated with a transparent metallic conductive coating on the bottom.

Engineer Project and Seminar: MICROWAVE BANDPASS FILTER :IDLE lumped filter
http://seminarengineer.blogspot.com/2011/08/microwave-bandpass-filter-idle-lumped.html
Engineer Project and Seminar. Saturday, August 27, 2011. MICROWAVE BANDPASS FILTER :IDLE lumped filter. In many microwave radio systems, waveguide filters are used as preselectors and diplexers. With highchannelcapacity systems, the filters must have a broad passband, high selectivity, low-insertion loss and a small differential or group. Relatively smaller size than the BPF having parallel coupled lines. Labels: MICROWAVE BANDPASS FILTER. Subscribe to: Post Comments (Atom). Touch Screen TECHNOLOGIES pag...
