Application: Delay line and mismatched transmission lines. A lossless coaxial transmission line with dimensions as shown in Figure 14.35a is given. In a circuit implementation that includes the line, it becomes necessary to delay the signal on the line by an additional 1 μs. Two options exist:
(a) A length of line identical to the given line is connected at the end of the line (between the line shown and the circuit). Calculate the required length of line to affect the required delay.
(b) A simulated line is made in the form of a ladder network of lumped parameter components as shown in Figure 14.35b. Design a network that will have the same characteristic impedance as the line and will provide the required delay. You are free to use as many sections as necessary to provide the delay.
(c) As an engineer, which method would you choose?
