ReciprocalFract32

Overview

Computes the reciprocal (1/x)

Discussion

Generates the reciprocal of the input signal on a sample-by-sample basis. \(out[n]=\frac{\displaystyle 1}{\displaystyle in[n]}\) Note that the module does not do any input checking and if the input is 0 then the output will be NaN.
