ABSTRACT:
A wireless digital communication system is a technique that allows people to communicate each other at a distance. In this paper we tried to explain one of the latest technologies of digital wire less communication systems - The CDMA and the application of this on cellular phones.CDMA is an acronym for code division multiple access. Each CDMA subscriber is given with a separate code for communication that reduces interferences & increases privacy. In this paper we explained about the transmission, rec ....etc

ELECTRONIC STETHOSCOPE



objective:

The aim of technology is to make products in a large scale for cheaper prices and increased quality. Stethoscopes are not only useful for doctors, but for home mechanics, exterminators, spying etc. Standard stethoscope provides no amplification which reduces its use for a certain extent .But an ELECTRONIC STETHESCOPE uses op-amps to amplify the signal and includes a low pass filter to remove background noise.

mems microphone stethoscope schematic

Abstract

This article is devoted to the investigation of MEMS microphone characteristics as an acoustic transducer of the electronic stethoscope. STMicroelectronics digital microphone MP45DT02 parameters were considered and significant physiological sounds were recorded. Also data obtained from MEMS and analog microphones were compared.The traditional acoustic stethoscope has been in use for nearly 200 years, changing very little over that time. As one of the most important diagnostic tools in a doctor s ....etc

Electronic Stethoscope-2

Assembly:

1) Assemble the circuit using Veroboard (stripboard) or a PCB.
2) Use a shielded cable for the microphone as shown on the schematic.
3) Fasten the microphone to the stethoscope head with a rubber isolating sleeve or use a short piece of rubber tubing on its nipple. A thick jar lid can be used as a stethoscope head. The microphone must be spaced away from the skin but the stethoscope head must be pressed to the skin, sealing the microphone from background noises and avoiding acoustical feedback w ....etc
