英国“电子工程”有一篇文章,曾介绍了有关数字滤波器及其优点。本文将对数字滤波器在远讯领域中的应用加以评述。由于集成电路的发展,尤其是大规模集成电路的发展,使近几年来对数字滤波器的关注与日俱增,因为,大规模集成电路的应用使数字滤波在经济上能与其它型式的滤波相比拟。尽管集成电路制造工艺不断发展,由于 An article in the British “Electronic Engineering” has introduced the digital filter and its advantages. This article reviews the application of digital filters in the field of remote sensing. Due to the development of integrated circuits, especially the development of large-scale integrated circuits, digital filters have been gaining more and more attention in recent years because the application of large-scale integrated circuits makes digital filtering economically comparable to other types of filtering. Despite the continuous development of integrated circuit manufacturing process, due
