Program for Section 9 in October. 2014 issue of the Transistor Gijutsu
(Japanese electronics magazine)

概要

このプログラムは、ソフトウエアDDSにより、任意の波形を出力（2ch）します。 特徴は次のとおりです。

  • PWM出力をDAコンバータとして利用します。
  • 周波数や波形、バースト条件などを個別に設定できる独立した出力を２チャネル持っています。
  • 周波数分解能0.023ｍHz
  • 周波数範囲0.023ｍHz～１０ｋHz
  • 各チャネルにそれぞれ、波形の先頭で出力されるトリガ出力があります。
  • 出力波形を関数で定義できます。
  • 休止波数、出力波数、を設定することでバースト波形が出力できます。

ファイル

このソフトウエアは、次のファイルから構成されています。

  • DDS.cpp - DDSによる波形発生
  • main.cpp - main()関数

詳細については、10月号の記事および上記ファイル中のコメントを参照してください。
