Abstract: The main aim of this assignment is to design a pre amplifier circuit with an NPN transistor to be used in a simple public address (PA) system. The pre amplifier is fed from a microphone that produces an average output voltage of 10 mV rms. The amplifier is to operate over a frequency range of 300 Hz to 5 kHz and should have an adjustable volume control. The expected gain of the amplifier is 100. First we are going to design an amplifier for given specifications‚ model the operation of the

QUESTION #1 Does the Universal Circuits’ Irish controller have a convincing argument for the weakness of the dollar? Why or why not? How would you interpret the evidence? The controller of the Irish division does have a valid point when stating that the U.S. dollar is in a vulnerable position due to the fact that its trade deficit is currently in excess of $100 billion and growing. (see Exhibit 1). While Universal Circuits’ chief financial officer‚ Joe Merrill‚ is correct when stating that

Another way Lewis could approach his dilemma would be the use the universal ethics theory. The universal ethics theory focuses on moral absolutism and the concepts of good and bad. The theory operates outside of cultural and religious norms and focuses on what is universally conceived as right and wrong. In this situation Lewis would

Subject – Supply Chain Management Semester - III Case - 1 John Deere and Complex Parts‚ Inc. On Friday‚ November 22‚ 2000‚ Blake Roberts‚ Hayley Marie‚ Stan Ealdns‚ and John Pearson‚ members of one of John Deere’s supplier evaluation teams‚ were discussing the performance of Complex Parts. It had provided questionable service to John Deere’s Moline unit over the past year‚ and they were wondering if this merited giving Complex Parts’ business to a different supplier. They needed

important role in the success of a person. However come to think of it‚ what really is success? Success is defined by an individual. Success can be defined as the financial stability of a person‚ his happiness‚ or perhaps self- fulfillment. In whatever case it may be defined‚ attaining college degree serves as a milestone to success. Although people who did not finish college have been successful for some‚ have been socializing in broader environment and have been learning through self-discovery‚ I believe

Why use regulated power supplies? The ideal voltage-regulated power supply would have the following features: 1. Zero output impedance at DC and at all frequencies 2. Zero regulation (constant DC output voltage) for a wide range of AC line voltages and over the entire range of load currents that are required by the powered circuitry. 3. Zero power dissipation. 4. Instantaneous recover from changes in line voltage and load current. 5. Overload protection so that normal operation is automatically

Power Tool Proposal – Task 3 In order to operate at maximum profit levels‚ a business must have lower operational costs than the competition. The means to satisfying lower operational costs is Supply Chain Management. Supply Chain Management is a cross-industry wide philosophy to improve operational efficiency by integrating activities of obtaining goods and services to create a product. When implementing a supply chain strategy‚ consideration must be given to the approach given to suppliers

BARGAINING POWER OF SUPPLIER • Bargaining power is the ability to influence the setting of prices. • The more concentrated and controlled the supply‚ the more power it wields against the market. • Monopolistics or quasi-monopolistic suppliers will use their power to extract better terms (higher profit margins or ) at the expense of the market. • In a truly competitive market‚ no one supplier can set the prices. Aggregation of Supply • Suppliers can group to wield more bargaining power. • This

is fairly straightforward and simple‚ right? Not exactly! Patricia Dunn was accused of hiring private investigators to investigate members of the board of Hewlett Packard. These investigators used a technique known as pretexting‚ a practice of getting your personal information under false pretenses (Federal Trade Commission‚ 2008). In this case the investigators called the phone company used by each of the board members‚ impersonated the board member‚ and gave personal information to gain access to
