[目次：検出系]

信号強度の再現能力を表す数値で、最大の信号レベルから雑音のレベルを引いたもの。デジタル信号のダイナミックレンジはビット数で表現される。

A quantity that expresses a reproducibility capability of the signal intensity. The "dynamic range" is defined as the intensity range obtained by subtracting the noise level from the maximum signal level. The dynamic range of the digital signal is expressed by the number of bits.
