Start you e-Portfolio by completingthe following steps. See the Quick Start Guide at http://sites.psu.edu/support/quick-start-guide/ for more detailsand screenshots.1. R eferring to Figure 1, create a site usi ng the following steps.(a) Open the web page sites.psu.edu and select Create A site.(b) Choose as the Site Name your Penn State Userid.(c) Choose as the Sit e Title your name f ollowed by ePortfolio(d) Allow your site to appear i n search engines by selecting yes under Privacy.Warning: Do not delete you e-Portfolio, as you will no longer be able to assign your Penn State Userid to theSite Name.Figure 1: Creating a site.2. Open the dashboard to your cite using the My Cites tab as shown in Figure 2.Figure 2: Creating the site dashboard.3. In order to select a theme, on the left menu of the dashboard, select Appearance and then Themes as shownin Fi gure 3. Select the theme Coraline to match the example e-Portfolio at http://si tes.psu.edu/jls32/.Figure 3: Selecting a theme.4. Use the banner ima ge EE-banner-spring2014.jpg, provided along with this problem set. Select the Header tabunder Appearance as shown i n Figure 4. Upload the file EE-banner-spring2014.jpg and the banner shouldappear as in Figure 5.Figure 4: Selecting a header.Figure 5: Upload the banner file EE-banner-spring20 14.jpg.5. Use the page tabs HOME, BLOG, GOALS AND SKILLS, WORK IN PROGRESS, WRITINGSAMPLES, and ACCOMPLISHMENTS, in this order, as shown in Figure 6.Figure 6: Required header and pa ge tabs.To add a page, follow Figure 7 and select the Add Pages tab under the Pages tab in the Dashboard.Figure 7: Required header and pa ge tabs.Following Figure 8, enter the tile of the first page, HOME. The Coraline template automatically capitalizesthe page name, in this case, HOME in the menu bar a ppearing above the banner. On the right hand side ofthe pag e, set the order to 0, as the HOME tab appears first in the list. Similarly, when generating the pagesBLOG through ACCOMPLISHMENTS, set the order numbers from 1 to 5 respectively. After you set upeach page, you must select the PUBLISH button on the upper right-hand side to save your work. In the nextproblem set, you will add content using theVisual tab.Figure 8: Window for adding a new page.6. Select the Widgets tab under Appearance on the dashboard, and remove all widgets in the Primary WidgetArea block on the right-hand side of the screen as shown in Figure 9.Figure 9: Remove all widgets appearing the Primary Widget Area.7. Select the General tab under Settings on the dashboard as shown in Figure 10. Set the Site Title to yourname, and under Tagline enter e-Portfolio as hown in Figure 11Figure 10: Selecting the General tab under the Settings tab of the dashboard.Figure 11: Set Site Title and Tagline fields.8. Use the full width (no sidebars) theme option. Under the dashboard, select Theme Options page underAppearan ce as shown in Figure 12. Choose the Full Width (No Sid ebars) option. You must click onSave Options button to update and save your site.Figure 12: Select the Full Width theme option.9. Under the dashboard, open the Reading tab under Settin gs. Choose the st atic page optio n and set theFront page to Home as shown in Figure 13.Figure 13: Select the static p age optio n and set the Front page to Home.10. Check your site and make sure that its format matches the example at http://sites.psu.edu/jls32/.Problem 2: (25 points)1. (8 points) Simplify the Boolean function F (x, y , z) = Σ(0, 2, 3, 5, 7) using the three-variable Karnaugh map inFigure 14.Figure 14: Three-variable Karnaugh map2. (8 points) Simplify the Boolean function F (w, x, y, z) = Σ(0, 1, 2, 4, 5, 6, 8, 9, 12, 13, 14) using the four-vari ableKarnaugh map in Figure 15 .Figure 15: Four-variable Karnaugh map3. (8 points) A do n’t-care minterm is a combinatio n of variables whose logical value is not specified. A don’t-careminterm cannot be marked with either a 1 o r 0 in a Karnaugh map, as this requires that the function be alway s1 or 0, respectively. Instead, an X inside a square in the Karnaugh map indicates tha t we don’t care whetherthe value of 0 or 1 is assigned to the function for a particular minterm. In choosing adjacent squares to simplifythe function in a map, the don’t-care minterms may be assumed to be either 0 or 1 , depending on which givesthe simplest expression. Consider a four-variable functionF (w, x, y, z) = Σ(0, 6, 8, 13, 14)which has the do n’t-care conditionsd = Σ(2, 4, 10).(a) (1 p oint) Using the form at in Figure 15, mark the minterms of F and d with 1s and Xs, respectively.(b) (7 points) Find a simplified expression for F .Problem 3: (25 points)The circuit in Figure 16 periodically flashes the neon bulb connected across the capacitor after the switch is cl osed att = 0. When the voltage across v(t) across the neon bulb is less than 50 volts, the neon bulb is off and is representedas an open circuit. When the voltage v(t) across bulb exceeds 50 V, the neon bulb glows an becomes equivalent toa 10 kΩ resistor. The neon bulb remains lit until the current i(t) through it drops below 3.5 mA, at which time thebulb will once again become an open circuit. There is no stored energy in the circuit before t = 0, and the componentvalues are R = 40 kΩ and C = 25 µF.Figure 16: Neon bulb flasher.1. (10 points) Determine the time t1when the bulb turns on.2. (5 points) Determine the current i(t) immediately after the bulb turns on.3. (10 points) Determine the time t2at which the bulb turns off.Problem 4: (25 points)This semester you will utilize a LM19 temperature sensor that generates an analog voltage that is a function oftemperature. Read the attached specification sheet that describes the operation of the LM19
