摘要:

The characteristics of the S‐curve in a symbol (bit) synchronizer are important in evaluating the timing‐variance performance. However, the calculation of S‐curve is so tedious and complicated that almost all the S‐curves in the literature are drawn by computer simulations. A simple and quick graphic approach to draw the S‐curve for a symbol synchronizer is proposed in this paper, which can provide exactly the same S‐curve as that with the conventional method for high SNR case.

摘要:

Stability study is essential in the control design of optimal quasi‐stationary tracking systems with parameter variations. In this paper, the asymptotic stability conditions of such systems given in the author's previous results [8, 13, 14] are developed. The conditions based on the design methods of traditional technique and model‐following technique can guarantee the closed‐loop system to be stable at the norminal conditions only. However, based on the guaranteed cost design technique, the closed‐loop system with allowable parameter variations is asymptotically stable because the guaranteed cost can be made to be a Lyapunov function for the closed‐loop system.

摘要:

The design of artistic fonts for characters is used for producing special visual effects via the shape and color changes on the character fonts. The various changes on the shapes of fonts can be achieved by changing the boundary curves of fonts which are represented by spline functions. In this paper, we focus our attention on the Chinese character fonts. A mathematical simulation of simplifying two dimensional and three dimensional surface projection is provided. The implementation of the system is presented with illustrative examples.
