example - they are satisfactory. If a filter capacitor is added after the rectifier diodes the output voltage waveform is improved considerably. Figures 3 and 4 show two classic circuits commonly used to obtain continuous voltages starting from an alternating voltage. The Figure 3 circuit uses a center-tapped transformer with two rectifier diodes while the Figure 4 circuit uses a simple transformer and four rectifier diodes.

Adaptive Shape Contour Tracing Algorithm by Emad Attalla‚ Ph.D. ABSTRACT In this paper we are going to present a new shape contour tracing algorithm called ¡§Adaptive Contour Tracing Algorithm¡¨. The algorithm can trace open and closed discontinuous digital shapes and return an ordered set of boundary points that represent the contour of the shape. Unlike other algorithms that return boundary points that are part of the traced shape‚ our algorithm returns background points that are adjacent

physicist John Fleming found that the Edison Effect also detected radio waves and converted them to electricity. In 1904‚ Fleming first showed off his two-element vacuum tube known as the Fleming diode that converted an alternating current (AC) signal into direct current (DC) (Kuphaldt). The Fleming diode consisted of an incandescent light bulb with an extra electrode inside. Electrons boiled off the surface of the metal plate and into the vacuum inside the bulb as the filament became white-hot. When

ECE 4752 Wafer Test Procedures In order to evaluate the electrical characteristics of the CMOS devices fabricated in ECE/ChBE 4752‚ a probe station is used to connect test equipment to the devices on-wafer. This is accomplished by positioning probes with mechanical manipulators such that their tips rest on metal pads on the wafer. Care must be
