FIR filter design with IEEE 754 half-precision floating point

Hi All We are in the initial phase of a project which implements processing of biomedical signals. I am trying to implement FIR filter with IEEE 754 half-precision (16-bit) floating point ari...

No ADC uses floating point format, also it's usage for signal processing is questionable. 16 up to 24 bit fixed point format seems to be more suitable.

Data width is a matter of signal dynamic (signal to noise ratio), not absolute signal level. Low level signal have most likely smaller signal to noise ratio and don't have so much significant bits.
