Investigation Of A Turner Circuit - Essay Example The lab report is detailed on the testing as well the design used in the construction of a tuner circuit. Being that students are supposed to actively take part in the practical in terms of setting frequencies before checking output waveforms, they become better at understanding the operation of the tuner circuit. In this report, therefore, emphasis is on assessing a tuner circuit in order to understand its features better. A circuit allowing an output only at a given frequency forms a tuner circuit. The use of a turner circuit is mainly in the communications industry for selecting of channels. Besides, it plays the role of a sub-system in that it concerts selected carrier frequency as well as its bandwidth into a fixed frequency that is in turn proper in processing from the received radio frequencies (RF). The AM/FM broadcast transmissions then feed the demodulator with the intermediate frequency (IF) and the demodulator in turn converts the radio signal into audio-frequency signals that enable driving a loudspeaker. Applications of wider frequency bandwidth are in transmissions that are more complicated such as DVB-S/DVB-T/DVB-D in digital TV, PAL/NTSC in TV and DAB for digital radio. Frequency bandwidths are equally transmitted as IFs with the use of several sub-carriers in the receiver. If the whole bandwidth undergoes sampling with A/D at a faster rate, the sub-carrier processing takes place (Learn about Electronics.com, 2011). The expected rate is at least twice the IF frequency.

Mid-term Exam - Essay Example een organization and customers or stakeholders in the current business economy would mean creation of new jobs, new products and services for customers, shareholder profit and growth of the economy (Van der Weide 27). Hence, I agree with Johnson’s view. c. Milton Friedman’s approach towards fiduciary duties was more practical and believed that profit maximization is a correct method to be socially responsible as a high-revenue earning company would provides higher benefits to the society through utilitarian work, thereby enhancing social welfare. Edward Freeman, on the other hand, would disagree with Johnson’s approach towards stakeholders. According to Freeman, it is the duty of fiduciary or organization to fulfill all stakeholder benefits, while Johnson has argued that stakeholder theory will not be applicable in practical situation (Johnston 30-40). d. The morals of CSR and stakeholder theory argue that stakeholder’s benefits such as, those of customers, workers and employees, should not be compromised. However, major objective of an organization’s board of director is that of profit maximization, which might compromise stakeholder’s benefits or CSR of the organization; for instance, closing a non-profit company results in unemployed workers at the expense of shareholder’s profit (Freeman and Liedtka 95-98). a. Based on Kelman’s analysis and further critics by known analysts, I disagree with most of the analysis. Nonetheless, Kelman’s analysis of cost and benefit method is right to certain extent. While it is flawed in terms of its applicability, it can still be useful and beneficial in certain areas such as, health and safety (D’Entrà ¨ves 33). b. The sustainability of cost-benefit analysis depends on accurately estimating individual benefits and costs. Inaccurate usage of models, over-reliance on past project’s data and information and subjective impression generates flawed results. Sustainability of the cost benefit analysis can be
