　音声や画像などをパソコンなどの計算機上で扱う場合、サンプリングされた信号として取り扱うことになる。このような形態で信号を取り扱う手法は、ディジタル信号処理技術として知られている。現在では、情報通信の分野はもちろん、広く工学分野において、ディジタル信号処理に関する理解が欠かせなくなってきている。

　そこで、本テーマではディジタル信号処理技術の基礎の一つである ディジタルフィルタを理解することを目的とする。具体的には、 インパルス応答からディジタルフィルタの特性を計算する方法や、 信号のフィルタリング処理(畳み込み演算)手順を理解し、プログラム の実装を行う。

Definition of a lens

Lenses

A lens is a custom view of Connexions content. You can think of it as a fancy kind of list that will let you see Connexions through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to Connexions materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual Connexions member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.
