A Sinusoidal Current Driver With an Extended Frequency Range and Multifrequency Operation for Bioimpedance Applications [PDF]

open access: yes, 2014
This paper describes an alternative sinusoidal current driver suitable for bioimpedance applications where high frequency operation is required. The circuit is based on a transconductor and provides current outputs with low phase error for frequencies ...

Temperature errors compensation in Coriolis vibratory gyroscopes

open access: yesMECHANICS OF GYROSCOPIC SYSTEMS, 2012
The effect of temperature variations on the output of Coriolis vibratory gyroscope (CVG) in general and with cylindrical sensitive element in particular via cross-damping is studied in this paper. Zero rate output of CVG is observed when temperature of the sensor varies. It is believed that temperature variations cause this bias through the temperature

Error Compensation for Area Digital Sun Sensor

open access: yesSensors, 2012
Compared to the error factors of the Linear Array Digital Sun Sensor (DSS), those of the Area Array DSS are complicated and methods used for error compensation are not valid or simple enough.

Live-timer method of automatic dead-time correction for precision counting [PDF]

open access: yes, 1969
Automatic correction for dead time losses in nuclear counting experiments is implemented by a simple live timer arrangement in which each counting interval is extended for compensation for the dead time during that interval.

Higher order error of discrete fiber model and asymptotic bound on multistaged PMD compensation [PDF]

open access: yes, 2000
We develop a random-matrix formalism that enables analysis of a variety of polarization-mode dispersion (PMD) related problems. In particular, we address the problems of higher order error in a discrete fiber model and limit of multistaged PMD ...
