cic
- 在信号处理中，信号发射时，信号通过载波，调制，以电磁波的形式发射出来 在接收端，射频信号通过天线接收，超外差式等方式进行处理，变频到中频 然后通过数字技术对中频信号进行处理，此时的中频信号采样率很高，多达几十兆赫 而要解调出来的信号很小，此时就要经过滤波来得到我们需要的信号 如果直接设计滤波器，阶数会非常庞大，软件，硬件设备都承受不了 因此，一般常用的技术是进行下变频处理，其主要技术就是通过抽取滤波进行下变频 常用的滤波器就是CIC抽取, 希望可以帮助一些坛友解决基本的问

field-2
- Field 2 是丹麦理工大学（Technical University of Demark）的J.A.延森（Jorgen Arendt Jenson）开发的一款超声模拟软件，该软件基于线性声场理论， 其最基本概念是空间冲击响应，最早由Tupholme和Stepannishen等提出，空间冲击响应是一个和何置相关的函数，它与换能器上的激励信号卷积，可以得到发射波到焦点的任意一点的声场。换能器接收同波信号相当与发射的逆过程，将空间的反射点作为发射源，与接收换能器的空间冲击响应卷积，从而得到回波信
