Abstract

The frequency counter has 6 digits and will work from 25MHz up to 200MHz.The best with this counter is that you don't need to connect it with any wires to your equipment. Wires=interference and drift in the oscillation frequency. This counter use a small pick up coil to probe the oscillation. Just hold the pickup coil a few cm from the main oscillator coil and read the LED.

The LED has 6 digits and the resolution is set to 1kHz.This counter is perfect to check that oscillators are working and at which frequency. ....etc

A Technique for Orthogonal Frequency Division Multiplexing
Frequency Offset Correction

Abstract:
The Orthogonal Frequency Division Multiplexing (OFDM) is a Multi Carrier Modulation technique employing Frequency Division Multiplexing of orthogonal subcarriers. It is also sometimes called as discrete multitone modulation (DMT). It is better than CDMA in high bit rate and Broadband Communications .It is a multi carrier technique, which is very sensitive to Frequency Offset between transmitter and receiver. Th ....etc

Our final project is to design and build a portable blood pressure monitoring device that can measure a patient's blood pressure and heart rate through an inflatable hand cuff. The device consists of three main parts: external hardware (such as the sleeve, motor, valve, and lcd), analog circuit, and microcontroller. The anode circuit converts the pressure value into the cuff into readable and usable analog waveforms. The MCU samples the waveforms and performs the A / D conversion to perform additional calculations. In addition, the MCU also con ....etc

Abstract:
A musical fountain is a type of animated fountain for entertainment purposes that creates an aesthetic design and sometimes a three dimension image. This is done by using the effects of timed sound wave and timed light or laser against water particles. The water refracts and reflects the light, and in doing so, a three-dimensional image cam be created.
Some are large scale, and use hundreds of water jets and laser emitters, the cost of which runs up into the millions of dollars, although smaller household forms exist where th ....etc

sim900 interfacing with atmega32

The GSM net used by cell phones provides a low cost, long range, wireless communication channel for applications that need connectivity rather than high data rates. Machinery such as industrial refrigerators and freezers, HVAC, vending machines, vehicle service etc. could benefit from being connected to a GSM system. Take a given example. A garage offers a very special package to their customers. Based on the mechanics knowledge and the given vehicle, tailored service intervals can be specified. A part of the s ....etc

Abstract:
This is one of great project based on AVR microcontroller. It use ATmega32 as processor and LCD 128 64 pixels for display. If you need to measure low frequency i thought this project, AVR oscilloscope, will be usefull. Maksimum frequency for AVR oscilloscope is 5 kHz (square signal), other signals (sine or triangle) the frequency is lower ( almost 1 kHz) for having clear view of the signal. Voltage input range is 24V AC / 30V DC.
This project use C language and CODEVISION as compiler. So, it will be more easy to understand t ....etc
