2.2 Definition of a Microcontroller Microcontroller‚ as the name suggests‚ are small controllers. They are like single chip computersthat are often embedded into other systems to function as processing/controlling unit. For example‚ the remote control you are using probably has microcontrollers inside that do decodingand other controlling functions. They are also used in automobiles‚ washing machines‚microwave ovens‚ toys ... etc‚ where automation is needed.The key features of microcontrollers include:

Using Pulse-Width Modulation and Audio Sampling Techniques to Construct an Audio Player with a Field-Programmable Gate Array John C. Greavu III University of Minnesota‚ School of Physics and Astronomy I. INTRODUCTION 8-bit and 16-bit audio players were built by employing pulse-width modulation (PWM) techniques with a field-programmable gate array (FPGA). Basic PWM and audio playing methods are explained in detail. A sigma-delta modulation module‚ specifically‚ was programmed into a Basys

Step Down DC to DC Converter Ivana Krezzel T. Almazan and Ruphina G. Gomez Introduction In our world today‚ cellphones‚ and laptops are widely used. For some‚ these things are so important especially for students and employers who work from office. These devices are usually operated with battery. A DC to DC converter is an electronic circuit which converts a source of direct current (DC) from one voltage level to another. DC is not easily being stepped up or down. One of the applications

offset from the stored charge. The capacitor forms a time constant with the resistor load which determines the range of frequencies over which the clamper will be effective. In electronics‚ a clipper is a device designed to prevent the output of a circuit from exceeding a predetermined voltage level without distorting the remaining part of the applied waveform. A clipping circuit consists of linear elements like resistors and non-linear elements like junction diodes or transistors‚ but it does
