The ability to noninvasively measure high frequency signals at the internal points of an integrated circuit is important in performing diagnostics of current high speed microelectronics. Conventional measurement techniques rely on direct electrical contact with a point on the circuit being monitored. These measurements are limited to predefined test points and are difficult to perform without disturbing...
In this paper we are highlighting the signals that are not Fourier transformable and give its Fourier transform using PCA (Principle Component Analysis), lDA (linear Discriminant Analysis). Such signals are step signal, signum, etc. Basically Fourier transform transforms time domain signal into frequency domain and after transformation describes what frequencies original signal have. Principle Component...
Multi-media based applications have increased immensely in the last few years. The need to have better video quality, higher recording and playback time, more video channels and faster time to market (TTM) requires DFT solutions that use core-based testing to allow concurrent IP and SOC development, scalable to support multiple technologies and eases the development of timing constraints. This paper...
This paper presents a new method that evaluates the manufacturability of microoptical systems. A statistical, kinematic link model is applied to compute the deviations of optical paths due to the positional and angular misalignments of optical components. The deviation of optical paths is a main source that deteriorates the performance of an optical system, hence it is very important to quantify how...
