Problem Description A 4 GHz high-frequency transmission system uses a coaxial cable to connect a transmitter to a Printed Circuit Board (PCB) Antenna. The PCB substrate is 1.55 mm thick, and the copper track is 0.035 mm thick. The coaxial cable has a characteristic impedance of 50 ohms, matching the transmitter's output impedance. However, the PCB antenna, designed for optimal radiation efficiency, has a different impedance of 150 ohms. Due to the impedance mismatch between the cable and the antenna, a portion of the signal is reflected back towards the transmitter. The reflected signals result in power loss, reducing the overall efficiency of the transmission system.

1. Consider a signal x[k] \begin{equation*} x[k] = \begin{cases} k & 0 \le k \le 3\\ 6 - k & k = 4,5\\ 0 & \text{otherwise} \end{cases} \end{equation*} a) Plot x[k] (1 mark) b) Determine the even part of x[k] and the odd part of x[k]. Call them $x_e[k]$ and $x_o[k]$ respectively. (4 marks) c) Determine the Fourier transform of x[k]. Call it X(?). (3 marks) d) Write down the real and imaginary parts of X(?). (Re{X(?)} and Im{X(?)}) (2 marks) e) What is the relationship between $x_e[k]$ and Re{X(?)} ? (1 mark) f) What is the relationship between $x_o[k]$ and Im{X(?)}?
