Was the existing system adequate in the past? Why or why not? Why is it no longer adequate? The existing system was adequate in the past due to heavy reliance on direct labor hours. The ETO served as a central cost center‚ and transferred the costs to other divisions at direct costs plus allocated burden. Being in the late 1970s and early 1980s‚ technology testing of components required fewer cycles‚ and less complicated structures. Hence‚ such testing on products could be carried out by direct

is rated at only 100 Vdc). FIGURE 3 From Figure 3: A diode in series with a resistor is connected across the inductor to resolve the arcing phenomena across the switch. At t 0‚ when the switch is opened‚ the diode is forward bias hence allowing current to its branch. The current‚ I in this circuit is then given by: (VL - VF ) /R ‚ where VF is the forward voltage drop of the diode. The stored energy in the inductor is dissipated as heat in the resistor. Consequently

mostly used for devices generating light based on the laser principle. The first laser device was a pulsed ruby laser‚ demonstrated by Theodore Maiman in 1960 [2‚ 3]. In the same year‚ the first gas laser (a helium–neon laser [5]) and the first laser diode were made. Before this experimental work‚ Arthur Schawlow‚ Charles Hard Townes‚ Nikolay Basov and Alexander Prokhorov had published ground-breaking theoretical work on the operation principles of lasers‚ and a microwave amplifier and oscillator (maser)

Chapter Three System Design and Methodology 3.1 Design Outline of the System The process of circuit design begins with the specification‚ which states the functionality that the finished design must provide‚ but does not indicate how it is to be achieved. The initial specification for this project is a dc voltmeter with an input voltage range of 0 to 300 volts. Although there are many parameters that a design specification should contain‚ such as size‚ weight‚ moisture resistance‚ temperature
