TMS320F2808
Summary:
Class D amplifiers have proven a higher power efficiency performance against linear classes such as Class A, B and AB. Power losses on Class D amplifiers are mainly due to non-ideality of the output transistors, operating as switches, controlled by Pulse Width Modulators. This example describes a method for ... audio-frequency content.

Class D amplifiers have proven a higher power efficiency performance against linear classes such as Class A, B and AB. Power losses on Class D amplifiers are mainly due to non-ideality of the output transistors, operating as switches, controlled by Pulse Width Modulators. This example describes a method for utilizing both the Enhanced Pulse Width Modulator (ePWM) and the Analog-to-Digital Converter (ADC) of the TMS320F2808™ digital signal controller as D-Class Audio amplifier. The method involves analog full bridge D-class power amplifier and analog low-pass filtering the amplified PWM signal to remove high frequency components, leaving only the audio-frequency content.

"Musical Signal Processing with LabVIEW," a multimedia educational resource for students and faculty, augments traditional DSP courses and supports dedicated courses in music synthesis and audio signal processing. Each of the learning modules blends video, text, sound clips, and LabVIEW virtual instruments (VIs) into explanation of theory and concepts, demonstration of LabVIEW implementation techniques to transform theory into working systems, and hands-on guided project activities. Screencasts -- videos captured directly from the computer screen with audio narration and a hallmark of this resource -- use a mixture of hand-drawn text, animations, and video of the LabVIEW tool in operation to provide a visually rich learning environment. *** Unlike other collections that contain sub-sets of modules from this course, this collection contains all modules. ***

The Audio Conference Bridge enables a voice call with multiple (n >2) attendants. The algorithm monitors the voice signals from all attendants, and creates the signals to be transmitted to the attendants. In this module the implementation of such a bridge is described, The implementation is based on the integration of user-specific driver with the Simulink environement building blocks.
