A digital filter performs digital filtering to process (preserve, attenuate, or modify) different spectral components of a signal. Digital filters have been serving various aspects of our daily life. Personal and home applications where digital filters are involved include mobile phone, hearing aid, headphone, loudspeaker, photography, songs and music, radio, movies, CD, DVD, HDTV, etc. Indeed, the fields of digital filter applications are broad which include communications; cable, radio, and satellite broadcasting systems; antenna, radar, and sonar systems; consumer and industrial electronics; control systems; electric power and machines; biomedical instrumentation; seismic system; remote sensing system; aerospace and transportation systems; enhanced vehicle applications etc. In general, a digital filter can be designed and implemented to meet the high accuracy requirement of a demanding application. However, the nature of nearly all applications of digital filters is to process a signal without making use of the dynamic information of the signal to achieve what can be called intelligent digital filtering. An intelligent digital filter that combines the computing power of a digital filter and the brain-like abilities to process information intelligently is expected to offer unprecedented performances in applications. Imagine an intelligent digital filter in any of your devices such as mobile phone, hearing aid, car radio, and HDTV DVD combo that can continuously monitor different noise environments and self-adjust its filter coefficients to produce a clear sound at a comfortable level. By representing a signal, image, video, genome or any type of information as a numerical waveform, an intelligent digital filter can manifest itself to process a variety of information, and has a scope that has no boundary. This research program on intelligent digital filters will advance their designs and applications and will offer a powerful and unprecedented filter for signal processing. The technology developed will inspire new ideas, methods, and applications; and will enable better living in a forthcoming intelligent digital filter age benefiting individuals, families, organizations, Canada, and the world.

数字滤波器执行数字滤波来处理（保持、衰减或修改）信号的不同频谱成分。数字过滤器已经服务于我们日常生活的各个方面。涉及数字滤波器的个人和家庭应用包括手机，助听器，耳机，扬声器，摄影，歌曲和音乐，广播，电影，CD， DVD，高清电视等。事实上，数字滤波器的应用领域很广泛，包括通信；有线、无线电和卫星广播系统；天线、雷达和声纳系统；消费和工业电子产品；控制系统;电力和机械；生物医学仪器;地震系统;遥感系统；航空航天和运输系统；增强车辆应用等。一般来说，数字滤波器可以设计和实现以满足苛刻应用的高精度要求。然而，几乎所有数字滤波器应用的本质都是在不利用信号的动态信息的情况下处理信号，从而实现所谓的智能数字滤波。智能数字滤波器结合了数字滤波器的计算能力和智能处理信息的类似大脑的能力，有望在应用中提供前所未有的性能。想象一下，在手机、助听器、汽车收音机和高清电视DVD组合等任何设备中都有一个智能数字滤波器，它可以连续监测不同的噪音环境，并自我调整其滤波器系数，以产生清晰舒适的声音。通过将信号、图像、视频、基因组或任何类型的信息表示为数字波形，智能数字滤波器可以表现为处理各种信息，并且具有没有边界的范围。这个智能数字滤波器的研究项目将推动它们的设计和应用，并将为信号处理提供一个强大的和前所未有的滤波器。所开发的技术将激发新的想法、方法和应用；并将在即将到来的智能数字过滤器时代实现更好的生活，使个人，家庭，组织，加拿大和世界受益。
