Development of high precision digital magnetometer

Development Of DSP Based Magnetometer

Magnetometer is essential for finding out orientation of any object using earth’s magnetic field. This is done by measurements of earth magnetic field along three perpendicular directions. In this design magneto resistive sensors are aligned in perpendicular directions are used for measuring the field. Sensor output voltages are digitized using ADC and send to DSP. Algorithms are implemented in...

Low-cost testing of high-precision analog-to-digital converters

High-Precision Frequency Measurement Using Digital Signal Processing

High-precision frequency measurement techniques are important in any branch of science and technology such as radio astronomy, high-speed digital communications, and highprecision time synchronization. At present, the frequency stability of some of atomic oscillators is approximately 1E-16 at 1 second and there is no sufficient instrument to measure it (C. A. Greenhall, 2007). Kinds of oscillat...
