课程名称：信号与系统本科课程（课程I） 课程概述：本课程是关于信号与系统的本科基础课程，是两门课程中的第一门，适合任何电气、电子、仪器或生物医学工程专业的学生。理解连续时间（CT）域和离散时间（DT）域的信号基础是必须的。课程深入覆盖了信号处理所需的所有基本知识，也可作为数字信号处理的复习课程。 课程内容组织与主题覆盖： 1. **信号简介**：该模块始于信号和系统的基本定义，详细解释了信号的主要分类和信号表示中的自变量。随后介绍了对自变量（如时间）进行的操作及其优先级。 2. **信号分类**：详细讲解了周期性和非周期性信号的分类，以及正弦信号和实数指数信号的具体例子。还对能量信号和功率信号进行了分类，最后解释了偶数信号和奇数信号的分类，并扩展至共轭对称和共轭反对称信号的分类。 3. **标准信号**：深入讲解了单位脉冲、单位阶跃和单位斜坡信号等奇异函数，图形和数学上在CT和DT域中的定义，解释了信号的性质及奇异函数之间的关系，还涵盖了符号函数、sinc函数等其他信号。 4. **系统属性**：系统的所有属性，如线性、时间不变性、因果性、稳定性、记忆性和可逆性等，均通过标准例子进行了充分解释。 作者介绍：Udaya Bhaskar先生是一位具有超过16年教学经验的本科大学教师和GATE辅导教师，专注于信号处理、半导体、数字设计及电子学基础学科。他已培训数千名学生为GATE和ESE考试做好准备。
This is an undergraduate course on signals and systems. This course is first one in a series of two courses on basics of signals and systemsFor any electrical, electronics, Instrumentation or bio-medical engineering student understanding basics of signals in continuous time(CT) domain and in discrete time(DT) domain is a must. This course gives an in-depth coverage of all the fundamentals required for signal processing in both the domains. This can also be taken as a refresher course to understand 'Digital signal processing'.The organisation and coverage of topics is as follows:Introduction to signals: This module begins with basic definition of signal and system. The primary classification of signals and independent variables in signal representation are well explained. Then we will move on to the operations performed on independent variable like time and their order of precedence. Classification of signals: Periodic and aperiodic signal classification is explained with sinusoidal signals and real exponential signals in detail. Another classification energy and power signals is given with all necessary examples. Finally, even and odd signals classification and its extension conjugate symmetric and conjugate anti symmetric signal classification is explained. Standard signals: An in-depth coverage of singularity functions like unit-impulse, unit-step and unit-ramp signals are given in this chapter. All these signals are defined graphically and mathematically in both CT and DT domains. Properties of signals and relation between singularity functions is also explained. And other signals like signum function, sinc function etc., are also covered.System properties: All the system properties that is Linearity, time invariance, causality, stability, memory and invertibility are well explained with standard examples.About Author:Mr. Udaya Bhaskar is an undergraduate university level faculty and GATE teaching faculty with more than 16 years of teaching experience. His areas of interest are signal processing, semiconductors, digital design and other fundamental subjects of electronics. He trained thousands of students for GATE and ESE examinations.
