ERRATA
Here are
comments turned in by students. I
haven’t had time to double check all of them but put them here in case you get
going on something and think there might be a mistake.
I noticed a typo on an example. This is from the 2004 midterm I and is linked to your lecture from September 3rd. The problem asks to find the voltage on the line 4.8 wavelengths from the load. However the labeled length between the input and the load is only 2.6 wavelengths. Hopefully that wouldn't hold anyone up as it's pretty clear you probably just meant to have 9.6 (as it's twice of 4.8). Just letting you know.
I believe I have found an error on Midterm I, 2007, from 8 September on the link 'Example Exam Question on Input Impedance (see problem 1)'.
Where I_load is calculated, the phase angle (in radians) should be -0.337 instead of -0.3695. The current in rectangular form is 0.2-j0.07, thus
arctan(-0.07/0.2)=-0.337
I know it's a small thing....but thought I'd let you know anyway.
