Description
「numberBands」を用いる「bsOttBands」の表現は〔式1〕における「numBands」を用いる表現とほとんど同様であるため、詳細な説明は省き、その式だけを以下に示す。
多数のTTTボックスの場合、「bsTttBandsLow」の組み合わせは「numberBands」を用いる〔式6〕乃至〔式8〕の意味は〔式2〕乃至〔式4〕の意味と同一であるので、〔式6〕乃至〔式8〕についての詳細な説明は省略する。
〔式9〕の意味は〔式1〕の意味と同一であるため、〔式9〕の詳細な説明は省略する。
〔式13〕の意味は〔式1〕の意味と同様であるため、〔式13〕の詳細な説明は省く。
