Estimation of the periodic parameter by the interpolation of the DFT gives the same effect as the reduction of the spectrum tails. The side-lobe suppression is at the cost of widening the main lobe, and with this, increasing the noise contributions. In this paper, we try to show a trade off between the reduction of the systematic error of the frequency estimation and the uncertainty of the estimated results due to the interpolation algorithm. The number of interpolated points depends on the noise level, and on the mutual positions of frequency components of the signal.","PeriodicalId":386903,"journal":{"name":"Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat.

The system, utilising imaging, spectral analysis and two-colour pyrometry techniques, is capable of monitoring the oscillation frequency and temperature distribution of up to eight flames concurrently and simultaneously. The relative error of the system for frequency measurement is less than 1% (0-100 Hz) whilst for temperature measurement it is no greater than 2% (1000/spl deg/C-1500/spl deg/C). Experimental results obtained on a simulated gas turbine have demonstrated that the fundamental frequency of the flame measured by the system responds in predictable ways to the excitation frequency of fuel flow. Further development is underway to apply the technique to a practical gas turbine combustor.","PeriodicalId":386903,"journal":{"name":"Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat.

This paper presents an algorithm for navigation on a chip that is based on localization of microscopic eye-point images using a previously acquired wafer map. It is fast enough for in-line microscopy and robust to visual changes occurring during the manufacturing process, such as contrast variations, re-scaling, rotation and partial feature obliteration. The algorithm uses geometric hashing, a highly efficient technique drawn from the object recognition field. Experimental results indicate high reliability of the algorithm.","PeriodicalId":386903,"journal":{"name":"Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat.

The topology we propose can be applied both at board level and an integrated circuit level when designing compact and low cost devices for automated test equipment (ATE). In fact, as it will be demonstrated in this paper, high accuracy can be guaranteed by design, without the need for any calibration procedure. The approach we propose can therefore be considered as a possible and advantageous alternative to the conventional methods employed for the realization of high accuracy, multiple outputs, programmable voltage or current sources. A prototype of a SAM based on the approach we propose has been realized and tested. As it will be shown, the experimental results we have obtained fully confirm the validity of our approach.","PeriodicalId":386903,"journal":{"name":"Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat.
