What Is Scilab? There exist two categories of general scientific software: computer algebra systems that perform symbolic computations‚ and general purpose numerical systems performing numerical computations and designed specifically for scientific applications. The best-known examples in the first category are Maple‚ Mathematica‚ Maxima‚ Axiom‚ and MuPad. The second category represents a larger market dominated by MATLAB. Scilab belongs to this second category. Scilab is an interpreted language

02XXX-WTP-001-A March 28‚ 2003 NRZ Bandwidth (-3db HF Cutoff vs SNR) How Much Bandwidth is Enough? White Paper Introduction A number of customer-initiated questions have arisen over the determination of the optimum bandwidth for any transimpedance amplifier and subsequent filter employed in a fiber optic receiver module using NRZ coding. When asked what the optimum bandwidth for such a system‚ most engineers will respond with a number between 0.7 and 0.75 times the NRZ bitrate. The real answer

Algorithms In OFDM Systems Vineetha Mathai Dept. of Electronics Engineering‚ Madras Institute of Technology‚ Chennai-600044‚ India. e-mail: vineethamathai@yahoo.in Abstract—The channel estimation can be performed for analyzing effect of channel on signal by either inserting pilot tones into all of the subcarriers of OFDM symbols with a specific period or inserting pilot tones into each OFDM symbol. The block type pilot channel estimation has been developed under the assumption of slow fading channel

Dynamic Signal Analyzer for dSPACE K. A. Lilienkamp‚ and D. L. Trumper Precision Motion Control Lab‚ MIT‚ Rm 35-030‚ 77 Mass. Ave‚ Cambridge‚ MA 02139 We have developed MATLAB software and a Simulink subsystem block which work in tandem to extract the transfer function (amplitude and phase) of a system using ‘swept sine’ excitation. The resulting dynamic signal analyzer provides a convenient tool for obtaining empirical Bode plots of system and controller dynamics within the dSPACE environment.

Kalman Filter and What Can It Do? A Kalman filter is an optimal estimator - ie infers parameters of interest from indirect‚ inaccurate and uncertain observations. It is recursive so that new measurements can be processed as they arrive. (cf batch processing where all data must be present). Optimal in what sense? If all noise is Gaussian‚ the Kalman filter minimises the mean square error of the estimated parameters. 3 What if the noise is NOT Gaussian? Given only the mean and standard
