We shall study the function of the PN generator in the context of the transmitter (Tx) and receiver (Rx) circuits by means of a simple example.

(B) A commercial 50 92 Radio Shake coaxial cable is used to carry RF signal power from a transmitter to an antenna of 300 2 as a load through flat antenna transmission line with 300 2 characterstic impedance as shown in Figure 3. The above situation would happen if we connect the coaxial cable to the antenna without a matching techinque. Determine: 1- The reflection coefficient at junction B. 2- The input impedance at point A. 3- The reflection coefficient at junction A. 4- The fraction of the reflected power. 5- The fraction of the transmitted power to the antenna. 1²=0 5052 30052 (B) Z₁ = 30052 Figure 3

a.What is the attenuation of 350 ft of RG-11 U coaxial cable at 100 MHz?b. A transmitter has an output power of 3 W that is fed to an antenna through an RG58A/U cable 20 ft long. How much power reaches the antenna?c. Two engineers have a disagreement over the selection of transmission line for connections within a 100m Data Centre on a project that is at risk for cost overrun. The first engineer is arguing in favor of using multi-mode fibre while the second engineer would like to use single mode fibre. You are the project engineer. Decide which of the two transmission lines to use and justify your answer.d. For typical silica optical fibres with ncore = 1.45 and Δ = 5 x 10-3, calculate nclad and NAe. For a typical silica fibre with D (@ λ = 1.3μm) = 2.5 nm ps/km and a semiconductor laser source centred on λ = 1.3μm with Δλ = 4nm: the bandwidth length BL ≈ 100 Gbps km (singlemode, step-index). What transmission speed is possible at a distance of 5km?f. A link from point a to point b is…
