The ratio of the power at a point to some arbitrary amount of power chosen as a reference. This ratio is usually expressed either in decibels based on 1milliwatt (abbreviated dBm) or in decibels based on 1 watt (abbreviated dBw).
以某个功率值作为参考量时某一点的功率与此参考量之比。这个比值通常用1毫瓦为基数 的分贝值(缩写为dBm)或以1瓦为基数的分贝值(缩写 为dBw)来表示。 |
