This course will mainly discuss on time-domain analysis and frequency-domain analysis of determined signal, description and characteristic of linear time-invariant system, as well as time-domain analysis and transformation domain analysis of signal via linear time-invariant system.

The project will develop a bandpass sigma-delta analog-to-digital converter for digital audio broadcasting system in three years. In the first year, we had finished the system simulation for IF receiver using conventional high speed ADC and bandpass sigma-delta ADC, respectively. We also had done the analysis and design of high-order bandpass sigma-delta modulator structure. In this year, we have developed a coefficient synthesis method for high order bandpass sigma-delta modulator using high order filter transfer functions (inverse Chebyshev bandreject filter function).

本计划将在三年内发展一个能应用在数位音讯广播系统的带通sigma-delta类比/数位转换器(analog-to-digital converter，ADC)，在第一年度中我们分别以传统高速类比/数位转换器及带通SD类比/数位转换器的接收系统为例，并结合编码正交多工器(Coded Orthogonal Frequency Division Multiplex，COFDM)的技术，建立一套DAB系统模拟的方法，同时并研究有关高阶带通SD类比/数位调变器的架构及电路，并已成功开发出一个由高阶滤波器合成的高阶带通调变器。

Upgrade of the pawn: When the pawn reaches the bottom line of the opponent, it may become any chessman except itself and the king, it may turn into any chessman among Queen, Rook, Knight, Bishop, or Cannon, and the change type is to be determined by the player, but the change must be undertaken.
