Bachelor thesis of this study has been designed to create a set of metrics and display the wireless heart sounds by sound signal detection of heart beats sending the blue surgical thapai II. The structure of the circuit is designed doiwongchon electronic fundamentals, which includes: Condenser microphone. Secret-signal amplifier wongchonkrong low frequency phase through the sequence 6, and an audio amplifier is the heart can process and display through your computer by using the MATLAB program that this tool can display the audio signals sent by the heart surgeon heart sound signal blue II thapai to resume.In the distance not exceeding 10 meters to calculate heart rate as well as recording information and details of the patient. Best results in detection of heart sound signal from the MATLAB program, an error of no more than 5 percent of all properties of the measuring instruments of signals and audio video wireless heart design in the master thesis. Study on the simulation to work with the program PSPICE and effect of real circuits in order to guarantee performance of the tool created.

This project is the study, design, build and display measurement instrumentation, wireless heart by detecting cardiac signals sent through Bluetooth to a computer. The structure was designed by basic electronic circuits. These include the Condenser Microphone Inverting amplifier Low pass filter through No. 6, and power amplifiers. Audio heart can be processed and displayed via computer using MATLAB programs, devices that can signal heart by being sent signals the heart via Bluetooth to a computer in the near term not exceeding 10 meters calculate the rate. Heart The data and details of the patient. The result of detecting the heartbeat signal from MATLAB programs are mistakes percent. 5 The properties of the measuring signal and display wireless heart design in this thesis. A study by mimicking the effects of working with PSPICE and the real circuit. To verify the performance of the tools created.

The dissertation studied the design of instrumentation measurement and display the wireless audio signal by detecting the heart via Bluetooth to the computer.The condenser microphone amplifier circuit. A return phase. The low pass filter and the 6 amplifier. Heart sound can process and display through a computer using MATLAB.No more than 10 meters, calculate your heart rate. The record information and details of the patient. The detection of heart sound signal from the program MATLAB error not exceeding.By imitating the work study program and the effect of PSPICE per cycle. In order to confirm the performance of the tool is built.
