Final answer:
The input impedance of a transmission line connected to the load ZL = 0.6 - j1.4 at the length of 0.307 λ can be calculated using the Smith chart.
Step-by-step explanation:
To calculate the input impedance of a transmission line connected to a load using the Smith chart, we need to determine the position on the chart that represents the load impedance and read the corresponding input impedance. In this case, the load impedance is given as ZL = 0.6 - j1.4 and the length of the transmission line is 0.307 λ. The Smith chart allows us to visualize the impedance transformation along the transmission line. By plotting the load impedance on the Smith chart and following the Smith chart's procedures, we can determine the corresponding input impedance.
