Just a note:�
When given a transmission line question, you may solve it either with calculation of equations or with Smith Chart.�� Smith Charts (like those in class) will be provided.� You may bring any other type of Smith Chart you like (colored, more detailed, preprinted, etc.).� Exam is open portfolio, open notes.�
