代码说明:

  信号的抽样和恢复,若 是带限信号,带宽为 , 经采样后的频谱 就是将 的频谱 在频率轴上以采样频率 为间隔进行周期延拓。因此,当 时,不会发生频率混叠;而当 < 时将发生频率混叠。(The signal sampling and recovery)

    说明:  机器学习是一门多领域交叉学科,涉及概率论、统计学、逼近论、凸分析、算法复杂度理论等多门学科。专门研究计算机怎样模拟或实现人类的学习行为,以获取新的知识或技能,重新组织已有的知识结构使之不断改善自身的性能。 它是人工智能的核心,是使计算机具有智能的根本途径,其应用遍及人工智能的各个领域,它主要使用归纳、综合而不是演绎。(Machine learning is a multi-disciplinary interdisciplinary subject, involving probability theory, statistics, approximation theory, convex analysis, algorithm complexity theory and other disciplines. It specializes in how computers simulate or implement human learning behavior to acquire new knowledge or skills, reorganize existing knowledge structures and continuously improve their performance. It is the core of artificial intelligence and the fundamental way to make computers intelligent. It is applied in all fields of artificial intelligence. It mainly uses induction, synthesis rather than deduction.)
