The dynamic range of operation of a system is measured by the ratio of the intensities of the largest and smallest inputs to the system. Typically, the dynamic range is quoted in the logarithmic units of decibel (dB), with 10dB corresponding to 1 order of magnitude. The largest input that a system can handle is limited by nonlinearities that cause appreciable distortion or failure at the output(s). The smallest input that a system can handle is limited by the system’s input-referred noise floor.
