Topic: DIGITAL FILTERS.

Expressions for a generalized Modified Transitional Butterworth-Chebyshev (MTBC) filter are derived. The characteristics of this filter as applied to digital filter design are investigated. It is shown that by adjusting location and order of the inserted zeros, the cut-off slope rate of the filter can be traded for maximum attenuation in the stop-band. The performance of this MTBC filter is compared to that of Butterworth, Chebyshev, transitional Butterworth-Chebyshev filters together with...

The linear discrete Kalman filter was analyzed using a frequency-domain approach. Process and measurement noise covariances are shown to be critical design parameters which, together with the assumed prior state and covariance estimates, completely determine the main schedule of the linear Kalman filter. Several relevant design techniques are illustrated and discussed. The concepts of smoothing and sharpening are demonstrated. Extensions to adaptive, nonlinear, and non-parametric filtering are...

A comparison of standard z transform and algebraic substitution synthesis methods for digital filters are presented with emphasis on the frequency domain characteristics. A generalization of Martin's procedure, which leads to recursive filters, is obtained. Also a new method to synthesize a digital filter from a magnitude squared versus frequency characteristic specification is presented.

Low Probability of Intercept (LPI) radars are a class of radar systems that possess certain performance characteristics causing them to be nearly undetectable by most modern digital intercept receivers. Consequently, LPI radar systems can oper-ate undetected until the intercept receiver is much closer than the radar.s target detector. The enemy is thus faced with a sig-nificant problem. To detect these types of radar, new direct digital receivers that use sophisticated signal processing are...

This thesis investigates the feasibility of automating the design of microprocessor-based digital filters. The ability of a prototype design system to successfully produce filter realizations is tested. General filter structures and programming algorithms are presented. Shortcomings in the current version of the design system are determined. Modifications are made as required to support digital filter realizations. The feasibility of filter generation is demonstrated using realistic examples...

Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI) radiometer brightness temperature data in the 85 GHz channel (T85) reveal distinct local minima in a regional map containing a Mesoscale Convective System (MCS). This is because of relatively small footprint size (approximately 5.5 km) and strong extinction properties in this channel of the TMI. A map of rain rate for that region, deduced from simultaneous measurements made by the Precipitation Radar (PR) on board the TRMM...

Noise generation caused by quantization of signals in digital filters is considered using matrix state-space techniques. The results are expressed in terms of the correlation of the errors so that the assumptions made about the statistical properties of the noise sources can be evaluated. The effect of correlation, which is shown to be significant, depends upon the specific structure of the filter and the relative location of the error source both topologically and temporally. Specifically, the...

Image filtering consists of modifying the original image by logically "reimaging" it with a mathematical imaging device in which spatial response can be controlled by the user . Image filtering is performed by a mathematical operation called convolution, which is simply the successive replacement of each point in the original image by a new value produced by a weighted combination of the original point and its surrounding neighbour points. Filtering generally requires definition...

The Hilbert transform allows small phase shifts to be clearly exhibited. The properties are studied of images obtained by Hilbert transform and also their development as a function of different experimental parameters. The Hilbert transform is obtained by placing a phase 'knife' in the spectral plane of a double diffraction setup. In addition, the precision is examined with which the phase knife must be placed and centered in the spectral plane and the effect of width of source used....

This research considers a new realization of digital filters suitable for VLSI implementation. The method involves delta modulation which provides analog-todigital (binary) conversion. The output of a linear system is the convolution of the input and the system impulse response. This new digital filter requires that both the input and the impulse response be first converted to bit streams using delta modulation. These bit streams are then convolved. The result is an analog voltage which...

Self adaptive filters adjust their parameters to perform an almost optimal filtering operation without apriori knowledge of the input signal statistics . Two approaches to the design of efficient self adaptive discrete filtering algorithms are considered. For non-recursive (FIR) adaptive filters, simplified estimations of the gradient of the performance function to be minimized are considered. These algorithms result in reduced complexity of implementation, improved dynamic operating range with...
