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

This article is devoted to how The Beatles changed music and how they inspired future artists to continue to change the world of music. Powell focuses on a song and then explains how the techniques used are innovative and the importance of these new styles. For example‚ The Beatles were the first band to use audio feedback in a music recording in the song “I Feel Fine.” Along with the new techniques‚ Powell describes the background to each technique and defines what each one is. For example‚ The

Karcher Drittes Physikalisches Institut‚ University of Gottingen‚ Gottingen‚ Federal Republic of Germany Active Impedance Control for One-Dimensional Sound Generalizing the concept of active sound absorption‚ a system for active impedance control has been developed‚ so far for plane waves at normal incidence. The active reflector is a loudspeaker driven by the incident sound wave. Its feeding signal is derived from a "wave separator" with two microphones splitting up the standing

How does a VSAT network work? A VSAT network has three components: • A central hub (also called a master earth station) • The satellite • A virtually unlimited number of VSAT earth stations in various locations - across a country or continent Content originates at the hub‚ which features a very large -15 to 36-foot (4‚5 -11m)- antenna. The hub controls the network through a network management system (NMS) server‚ which allows a network operator to monitor and control all components

Principles of Sigma-Delta ADCs Abstract: This article covers the theory behind a Delta-Sigma analog-to-digital converter (ADC). It specifically focuses on key digital concepts of oversampling‚ noise shaping‚ and decimation filtering. Introduction Sigma-delta converters offer high resolution‚ high integration‚ and low cost‚ making them a good ADC choice for applications such as process control and monitoring. The analog side of a sigma-delta converter (a 1-bit ADC) is very simple. The digital side
