Audio Amplifier Circuit



In the first part of lab#1 you will construct a low-power audio amplifier/speaker driver based
on the LM386 IC from National Semiconductor. The audio amplifier will be a selfcontained, battery-operated component. In the second part of the lab you will construct a
microphone circuit using a compact electret condenser microphone cartridge. These circuit
modules are important building blocks of many audio communications systems, and will be
used in our ultrasonic transceiver system. ....etc

In the output stages of most broadcastreceivers and some amplifiers,there is a limit up to which maximumpower can be developed withoutdistortion. In the widely acceptedoutput circuit, two output transistorsare connected in series between thepositive and ground and biasing is adjustedso that each transistor gets halfthe supply voltage.The circuit presented here is asimple audio amplifier for a personalstereo system. In this, supply voltageto each transistor can be enhanced toproduce a larger output. The audiodriver transformer drives the transis ....etc

Abstract:

A digital audio broadcasting system that is capable of providing a large number of high quality stereophonic channels to mobile receivers in an environment with severe multipath delay and fading. Optimum combination of frequency and time diversity to guarantee robust performance in the mobile channel, with its multipath delay and frequency-selective fading effects. The system is based upon a dynamic single channel per carrier assignment of each stereo channel to many carriers. Inter symbol interference degradations caused by multipat ....etc

Circuit of an automatic switch for audio power amplifier stage is presented here. The circuit uses stereo
preamplifier output to detect the presence of audio to switch the audio power amplifier on only when
audio is present. The circuit thus helps curtail power wastage. IC1 is used as an inverting adder. The
input signals from left and right channels are combined to form a common signal for IC2, which is used
as an open loop comparator. IC3 (NE556) is a dual timer. Its second section, i.e., IC3(b), is configured
as mono ....etc

Faurecia Exhaust Systems AB develops and manufactures exhaust manifolds for the car industry. In the developing process the FE-models are one of the main tools and they are becoming more and more important in the automotive development. In the tough competition between the manufacturers, the demands for fast development require good FE-models both from the manufacturers and their subcontractors.The main goal of this thesis is to update an existing FE-model of a close coupled exhaust manifold and look at the catalyst to investigate the behavior ....etc

Microsoft Access is a Relational Database Management System (RDBMS), designed primarily for home or small business usage. Access is known as a desktop database system because it's functions are intended to be run from a single computer. This is in contrast to a server database application (such as SQL Server), where it is intended to be installed on a server, then accessed remotely from multiple client machines. Microsoft (or MS) Access is a software package that you install just like any other software package, and is bundled as part of the Mi ....etc

Digital Audio's Final Frontier-Class D Amplifier

Digital technology continues its march from media like CDs and DVDs toward your audio speakers. Today, amplifiers based on digital principles are already having a profound effect on equipment efficiency and size. They are also beginning to set the standard for sound quality.

An old idea, the Class D amplifier has taken on new life as equipment manufacturers and consumers redefine the musical experience to be as likely to occur in a car, on a personal stereo, or on an a ....etc

Hi,
Im sweatha, I'm doing my final year B.E..As I'm doing project on secure and practical outsourcing of linear programming in cloud computing.
Abstract of this project is shown below..
Cloud Computing has great potential of providing robust computational power to the society at reduced cost. It enables customers with limited computational resources to outsource their large computation workloads to the cloud, and economically enjoy the massive computational power, bandwidth, storage, and even appropriate software that can be s ....etc
