Suppose we have a function which is sampled by a sampling time 10ms. This function comes in to the computer, then this computer should calculate square root (for every sampling time) from that function.
$ g^*(t) = \sqrt{f^*(t)}$
Here $f^*$ and $g^*$ are sampled signals (discrete)
Only these operations are possible:
Arithmetic shift, inversion, bit wise
Is there any well know square root calculation algorithms appropriate for this situation?
