LASER TORCH BASED VOICE TRANSMITTER AND RECEIVER
Using this circuit you can communicate with your neighbors wirelessly. Instead of RF signals, light from a laser torch is used as the carrier in the circuit. The laser torch can transmit light up to a distance of about 500 meters. The phototransistor of the receiver must be accurately oriented towards the laser beam from the torch. If there is any obstruction in the path of the laser beam, no sound will be heard from the receiver. The transmitter circuit (Fig. 1) comprises c ....etc

Abstract”

In this work we propose a method to identify the raga of a Carnatic music signal. Raga is analogous to melody in Western music but is much richer and stronger in its representation. The main motive behind Raga identification is that it can be used as a good basis for music information retrieval of Carnatic music songs or Film songs based on Carnatic music. The input polyphonic music signal is analyzed and made to pass through a signal separation algorithm to separate the instrument and the vocal signal. After extracting the ....etc

Introduction of IR music transmitter and receiver



Abstract

The infrared radiations are transmitted and received by ir leds and photo transistor respectively
The project emphases the way by which music is generated and driven by ir rays
The main idea behind this project is to generate musical notes by infrared radiations
The circuit uses popular melody generator IC UM66.
It can be used in wireless music systems.

IR-BASED VOICE TRANSMITTER AND RECEIVER


INTRODUCTION:

IR-BASED VOICE TRANSMITTER AND RECEIVER, the aim of the project is to communicate wirelessly. In this project we are using various transistors, LED, op-amp etc. and we made a detailed study on this so as to effectively use them in our project.

1.1 OBJECTIVE OF THE PROJECT: -
The aim of the project is to communicate between any 2 distant places wirelessly which are at a distance of 5meters apart. The distance can be improve ....etc

ABSTRACT

The DS - CDMA is expected to be the major medium access technology in the future mobile systems owing to its potential capacity enhancement and the robustness against noise. The CDMA is uniquely featured by its spectrum spreading randomization process employing a pseudo-noise (PN) sequence, thus is often called the spread spectrum multiple access (SSMA). As different CDMA users take different PN sequences, each CDMA receiver can discriminate
and detect its own signal, by regarding the signals transmitted by other u ....etc
