Dynamic Range(dB)=动态范围(dB)
Floating Point=浮点
Fixed Point=定点
Fixed =定点
Dynamic Range for floating point is determined by the size of the exponent
=浮点的动态范围由指数的大小决定
6 dB×255 exponent levels=1530 dB
=6 dB×255指数级=1530 dB
Dynamic Range for fixed point is determined by the data word size
=定点的动态范围由数据字的大小决定
