چکیده

− A piezoelectric accelerometer output voltage with zero shift was induced by the low-frequency response of the charge amplifier. So we designed a virtual amplifier with same input-output characteristic as the charge amplifier, and shock sensitivities of a piezoelectric accelerometer were evaluated by applying the input acceleration to the virtual amplifier. The shock sensitivities were comparable to the vibration calibration results.

Real Time Calibration of Strap-down Three-Axis-Magnetometer for Attitude Estimation

Three-axis-magnetometers (TAMs) are widely utilized as a key component of attitude determination subsystems and as such are considered the corner stone of navigation for low Earth orbiting (LEO) space systems. Precise geomagnetic-based navigation demands accurate calibration of the magnetometers. In this regard, a complete online calibration process of TAM is developed in the current research t...

Low Settling Time All Digital DLL For VHF Application

Settling time is one of the most important parameter in design of DLLs. In this paper we propose a new high speed with low settling time Delay Locked Loop (DLL) in which a digital signal processor (DSP) is used instead of using phase-frequency detector, charge pump and loop filter in conventional DLL. To have better settling time, PRP conjugate gradient algorithm is used to optimize delay of ea...

Automated Methods for Estimating Baseflow from Streamflow Records in a Semi Arid Watershed

Understanding of the runoff generation processes is important in understanding the magnitude and dynamics ofgroundwater discharge. However, these processes continue to be difficult to quantify and conceptualize. In this study,two digital filter based separation modules, the Recursive filtering method (RDF) and a generalization of therecursive digital filter (GRDF) were1991–2002 in the Hableh Ro...

Digital Acceleration of Correlation-Based Digital Background Calibration in Pipelined ADCs

We present here a general digital method to accelerate correlation-based digital background calibration in pipelined ADCs. The central task in correlation-based background calibration is the extraction of component mismatch information from correlated data sequences. Using an explicit frequency domain analysis, we treat the extraction process as discrete-time low pass filtering. We then show th...
