In a radio frequency circuit, a resistance of 1752 Ω serves as a load at the end of a 50 Ω transmission line. We wish to connect an inductor, L, in series to the input of the line so that a source with an output impedance of 50 Ω does not see reflections. No need to know the frequency to solve the problem (a) Determine the minimum length of the transmission line in terms of wavelengths. (b) Determine the value...
