通过本课程设计使学生深入理解和掌握ASK通讯系统的各个关键环节，包括基带信号形成、调试、解调、滤波、传输、噪声对通信质量的影响等。在数字信号处理实验课的基础上更加深入地掌握数字滤波器的设计原理及实现方法。使学生对ASK系统各个关键点的信号波形及频谱有深刻的认识。-Through the curriculum design so that students understand and grasp the depth of communication systems ASK all key links, including the formation of base-band signals, debugging, demodulation, filtering, transmission, noise on the communication quality and so on. In digital signal processing based on the experimental classes more in-depth grasp of the principle of digital filter design and implementation. ASK students to the key points system and the signal waveforms have a deep understanding of the spectrum.
