For example, consider the frequency response of the . ?ebo=z53fb M endstream endobj 46 0 obj 131 endobj 14 0 obj << /Type /Page /Parent 9 0 R /Resources 15 0 R /Contents 25 0 R /MediaBox [ 0 0 612 792 ] /CropBox [ 0 0 612 792 ] /Rotate 0 >> endobj 15 0 obj << /ProcSet [ /PDF /Text ] /Font << /TT2 21 0 R /TT3 30 0 R /TT4 19 0 R /TT6 23 0 R /TT7 17 0 R /TT9 26 0 R /TT11 28 0 R >> /ExtGState << /GS1 35 0 R >> /ColorSpace << /Cs6 24 0 R >> >> endobj 16 0 obj << /Type /FontDescriptor /Ascent 891 /CapHeight 0 /Descent -216 /Flags 98 /FontBBox [ -547 -307 1206 1032 ] /FontName /NJOAML+TimesNewRoman,BoldItalic /ItalicAngle -15 /StemV 133 /XHeight 468 /FontFile2 43 0 R >> endobj 17 0 obj << /Type /Font /Subtype /Type0 /BaseFont /NJOBBK+SymbolMT /Encoding /Identity-H /DescendantFonts [ 39 0 R ] /ToUnicode 18 0 R >> endobj 18 0 obj << /Filter /FlateDecode /Length 290 >> stream 0000004925 00000 n The function of a TL is to transport power from sources to loads with minimal loss. Transmission line is a linear system So make a Thevenin equivalent circuit looking in from the load end Vth(t) th R CL Rth =Zo This holds even if the source impedance were not matched to the time domain) +-(), polyethylene) Solution to Practice Set #1 Problem 1 4. This is the general definition of a transmission line. 0555 2 10 5. School of Engineering 5. 0000007647 00000 n This is followed by a detailed study of magnetostatics, covering BiotSavart law, Lorentzs force law and Amperes circuital law. Examples of transmission lines include coaxial cables, and simple 2-wire (Lecher) lines. (10 pts) 4T /0 n S 3 Spring 2008 Therefore, the power flow through a transmission line depends on the angle between the input and output voltages. A 100- lossless transmission line is terminated with load impedance: ? = 50 + 40 .The line is operating with a wavelength of 10 m.

J. Peterson Jr. and Sven Hoffmann, Transmission & Distribution World Magazine, (Aug/2006).
