Your grade will be based on what you filled in on the exam. This will be compared to your scratch work to make sure your work led to the answer given. The scratch paper is scanned in and effects your grade. You will not get a grade if you do not scan in your work sheet.   Once you complete the exam, Show all of your written work page by page to the camera clearly in the correct sequence. Submit your exam. Then you will need to scan all the pages with your work shown in one PDF file and upload the file into the Midterm Exam Upload Link.  USE A SCANNER OR SCAN APP, (such as Genius Scan for iPhones and other free scanner apps for Android), AND LOAD A PDF FILE. Do not produce a color file, only black & white files will be accepted. Before uploading, inspect your file and make sure that: 1. All pages are clearly readable. 2. No part of any page has been missed by the scanner, include cheat sheets also 3. All pages are contained in the file in the right sequence. 4. Each page is numbered and has your name. If your work does not match the answers in your exam your grade will be impacted. You have 10min to upload the file after you close Honorlock.    

This is part of problem 4. What is the Diode 1 voltage vD1 when the Diode 1 current is ID1=6mA? Please answer to the nearest millivolt. 

This is part of problem 4. What is the saturation current IS for Diode 1? Choose the closest answer.  Hint: pick a well defined current-voltage point. 

Part 3 . You are given the following diode circuit. Please answer the following questions and show your work on the scratch paper.  R2 = 2kohms, R1 = 1kohms Match with closest answer, you may reuse numbers.

Part 2 . The Miller Integrator below has R1=1kohm and C1=10uF, and starts at t=0 with vI(0)=vO(0)=0. A voltage ramp is applied between t=0 and t=1ms, such that vi(t)=2000t, where t is the time in seconds, and after 1ms the ramp reaches a voltage of 2V. (The ramp rate is 2V/ms). The ramp waveform is illustrated on the left. (Note: the ramp is only applied for 1ms). Answer the following questions.  Match with closest answer, you may reuse numbers.  

Part 1  Use the ideal Op Amp circuit below to answer the following questions. Make sure to show your work on your scratch paper, including the answer with units.  Po is the power to the load, Pi is the power supplied by source Vs. Vs = 2V, Ri = 1kohms, Rf = 4kohms, RL = 2kohms Match with closest answer, you may reuse numbers.

Part 3 . You are given the following diode circuit. Please answer the following questions and show your work on the scratch paper.  R2 = 4kohms, R1 = 2kohms Match with closest answer, you may reuse numbers.

I understand that failure to keep my eyes consistently ahead will result in either a 50% reduction or a zero on the exam at the instructor’s discretion.   I also understand that I may not wear caps, hoodies, or other items which shield my eyes from the webcam, nor may I use ear buds while testing. 

Weights, in grams, of a particular part were recorded and broken down as follows: : 5  This question is part of a quiz or exam at Arizona State University.  No portion may not be posted to any website, photos and screenshots may not be taken, and no portion of it may be printed out.   Perform a Chi-Square Goodness of fit test on this data to determine if it has the continuous uniform pdf between 0 and 2.5.  How many degrees of freedom does the test statistic have?
