Transistor Biasing Materials and Equipment: Materials: Hardware Parts (In the Toolbox): An NPN transistor: 2N3904 Four resistors: 1 k?, 470?, 3 k? and 6 k? Jumper wires Equipment: Hardware Equipment: Breadboard NI myDAQ Instrument device Screw Driver Screw Terminal connector USB CABLE Multimeter with probes Multimeter from NI ELVISmx Instrument Launcher Procedure: *** This lab has to be implemented only in hardware (using NI myDAQ) *** Analyze the circuit in the Figure 1 below to calculate the following values: VBB, VE, IE, VC and VCE. Make sure to include 20% tolerance for each resistor in the calculations. Construct the circuit shown in Figure 1 below on the breadboard using the transistor and two resistors (RCand RE). figure 1 Figure 1 Using the jumper wires, screw driver and screw terminal connector, connect the board to NI MyDAQ Instrument Device. Use channel +15V pin out on the NI myDAQ Instrument Device to provide the supply voltage (VCC). Use channel AI0 to measure the required voltages: VBB, VE and VC and currents: IC and IE using the Multimeter. Tabulate the data from step 1 and step 5. Calculated Measured VBB VE VC IE IC Short the resistor R2 and calculate the values in steps 1. Modify the circuit in Figure 1 to short the resistor R2 and measure the values in step 4. Measured values with R2 shorted VBB VE VC IE IC Review questions: Compare a calculated and measured values in the table. Discuss whether the values are the same of different. If they are different, provide the reasoning. And how to reduce this difference between calculated and measured values. What happens when R2 is shorted? Why does the measured values change? If the NPN transistor is replaced with a PNP transistor, how does the change in the transistor effect the current and voltage in the circuit? Deliverables: Analysis of the circuit and calculations of voltages: VBB, VE and VC and currents: IC and IE. Place your student ID card on the breadboard and take a picture of the circuit board and pin out on the NI myDAQ Instrument Device. Take screenshots of the measurements obtained from function generator and Multimeter on the NI ELVISmx Instrument Launcher on your screen. Lab Report: Use the Lab report template found in the ?Tools and Template? link in the navigation center. Include all the deliverables. Include all the screenshots of the measurements from circuit design on the breadboard using NI myDAQ Instrument Device and measurements from MI ELVISmx Instrument Launcher.

business pitch

PowerPoint Presentation with Speaker Notes.

Create a business pitch for your business plan in a 20- to 25-slide Microsoft? PowerPoint? presentation that addresses the following:
Company
Headline
Problem Worth Solving
Our Solution
Target Market
Competitive Landscape
Funding Needs
Sales Channels
Marketing Activities
Forecast
Milestones
Team and Key Roles
Partners and Resources
Hints from the Instructor:
For this assignment, i usually suggest that you start by making a case that shows the need. Make it dramatic/attention grabbing if possible. Are there any safety concerns or risks in the current situation? Use news stories from the past year if possible. Then present your vision and mission statements. Focus on the big picture.

Under Problem Worth Solving, be more basic. You are looking at your customer’s needs. e.g. You will not succeed unless you do this!

Then your solution is based on the vision you have presented.

Once you have presented a clear technical view of what you are offering.

Then make the case as to why should the customer investor trust/partner with/believe in you? Why are you better than your competition? Try to hit all the items in the assignment instructions (Company, Headline, Problem Worth Solving, Our Solution, Target Market, Competitive Landscape, Funding Needs, Sales Channels, Marketing Activities, Forecast, Milestones, Team and Key Roles, Partners and Resources)

General Notes: Sides need to be background and mostly titles or SHORT bullet points. Although the text on the slide is not meant to be read, it must be readable. Hit the highlights only and save the details for hand outs or put them in the speaker’s notes. Put citations in the speaker’s notes.

Present financial summaries and projections. Have you accounted for paying yourself? Put the financials last since that is your “ask.”

Make sure to include media (pictures, clip art, text art, etc.)

It all flows from a clear articulation of the problem!

Individual Assignment: Business Pitch

Purpose of Assignment

This assignment requires students to provide a snapshot of their proposed company and business idea. Working with a business plan is a great way to design and communicate the company?s course of action with prospective investors. It also provides lenders with insight to the business growth strategy to help secure funding. Students will learn the practical application of summarizing their pitch to prospects and organizing their business ideas in a logical manner.

Resources Required

Your text identifies three models derived from decision-making theory. Identify those models with examples of each.
List the steps, and explain the rationale, that decision makers should take when confronted with an ethical issue.

statistical significance

This will be a two part assessment
PART ONE:
When we examine the relationships between variables where two or more variables are characterized by nominal or categorical groups, we may use a chi-square test of significance. The chi-square test examines the statistical significance of the differences between observed and expected frequency count in each cell of the table. The chi-square test tells you only whether a statistical significance of difference exists between groups on some other categorical variable (neither strength nor direction).
