  1. The ratio of signal level to noise level ( sn ratio ) is a very important index for vtr and the noise is chiefly from magnetic recording system

    信噪比是評價錄像機性能的一個重要指標,而錄像機的噪音主要來源於磁記錄系統。
  2. Sn signal noise

    信號噪音比值
  3. It is more suitable to the practice using qlf to measure quality. this paper discusses the defect of quadratic loss function and studies the models of inverted normal and inverted gamma loss function. we explore the relationship between qlf and signal - to - noise ( sn ), put forward multivariate qlf model based on sn, which overcome the flaw that single - characteristic can not reflect multi - characteristic in practice

    本文討論了二次損失函數模型的局限,在此基礎上研究了逆正態、逆伽瑪損失函數模型;探討了質量損失函數與信噪比的關系,提出了基於信噪比的多元質量損失函數模型,克服了單質量屬性不能反映實際中多維質量屬性的質量損失的弊端,實例證明該方法是可行的。
