change acoustic energy into electrical energy. The heart sound signal is then processed by preamplifier and amplified to achieve the high gain and filter is used to give the desired audible heart sound which is sent wirelessly using RF module at receiver side. Indeed more than one doctor can play the heart sound and can do auscultation easily. The PC connectivity is also made available so that the captured data can be sent to pc for storage purpose and software analysis using think lab. Video can

MIMO Systems and Transmit Diversity 1 Introduction So far we have investigated the use of antenna arrays in interference cancellation and for receive diversity. This final chapter takes a broad view of the use of antenna arrays in wireless communications. In particular‚ we will investigate the capacity of systems using multiple transmit and/or multiple receive antennas. This provides a fundamental limit on the data throughput in multipleinput multiple-output (MIMO) systems. We will also develop

PART II I/O MODULES CHAPTER 7 UART 7.1 INTRODUCTION Universal asynchronous receiver and transmitter (UART) is a circuit that sends parallel data through a serial line. UARTs are frequently used in conjunction with the EIA (Electronic Industries Alliance) RS-232 standard‚ which specifies the electrical‚ mechanical‚ functional‚ and procedural characteristics of two data communication equipment. Because the voltage level defined in RS-232 is different from that of FPGA I/O‚ a voltage

Asynchronous communication utilizes a transmitter‚ a receiver and a wire without coordination about the timing of just how long the transmiter leaves the signal at a certain level to represent a single digital bit. Each device uses a clock to mesure out the ’length’ of a bit. The transmitting device simply transmits. The receiving device has to look at the incoming signal and figure out what it is receiving and coordinate and retime its clock to match the incoming signal. Sending data encoded

telephone has been adapted into the vocabulary of many languages. It is derived from the Greek: τῆλε‚ tēle‚ farand φωνή‚ phōnē‚ voice‚ together meaning distant voice. The essential elements of a telephone are a microphone (transmitter) to speak into and an earphone (receiver) which reproduces the voice of the distant person. In addition‚ most telephones contain a ringer which produces a sound to alert the user when a telephone call is coming in‚ and a dial used to enter a telephone number when initiating

reasoning behind how this could produce a signal. We know that electromagnetic radiation is produced by accelerating charges. In the radio transmitter‚ electrons oscillate up and down and are thus accelerating. An electron will exert a force on another electron when they are some distance away‚ like charges repel. When the electron in the transmitter oscillates up and down‚ the direction of the force it exerts changes since the source of the force is moving. It takes some time for the change

The chips that will be embedded in various devices contain transmitter and receiver built to send and accept data in digital format. In this paper we will discuss about red tacton‚ and it’s working states‚ and applications of red tacton in various fields. And we will compare our red tacton with the other
