Digital audio uses pulse-code modulation and digital signals for sound reproduction. This includes analog-to-digital conversion (ADC)‚ digital-to-analog conversion (DAC)‚ storage‚ and transmission. In effect‚ the system commonly referred to as digital is in fact a discrete-time‚ discrete-level analog of a previous electrical analog. While modern systems can be quite subtle in their methods‚ the primary usefulness of a digital system is the ability to store‚ retrieve and transmit signals without any

Efficient Energy Harvester for Microbial Fuel Cells using DC/DC Converters Abstract— Microbial fuel cell (MFC) is an emerging technology for sustainable energy production. An MFC employs indigenous microorganisms as biocatalysts and can theoretically convert any biodegradable substrate into electricity‚ making the technology a viable solution for sustainable waste treatment or autonomous power supply. However‚ the electric energy currently generated from MFCs is not directly usable due to the low

Hence we go for Ocean energy with Gaint Sea Snake - ( Pelamis Wave Energy Converter). About Wave Energy: Wave energy is a concentrated form of solar energy: the Sun produces temperature differences across the globe‚ causing winds that blow over the ocean surface. These cause ripples‚ which grow into swells. Such waves can

26‚ NO. 2‚ FEBRUARY 2011 399 A Nonlinear-System Approach to Analysis and Design of Power-Electronic Converters With Saturation and Bilinear Terms Tingshu Hu‚ Senior Member‚ IEEE Abstract—Power-electronic converters are intrinsically nonlinear. This paper proposes a Lyapunov approach to analysis and design of a class of nonlinear systems arising from power-electronic converters. The system has a bilinear term as the product of the state and the input—the duty cycle‚ which is subject
