(8.D.2.5) 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.

Type Definition

typedef struct _ModuleReciprocalFract32 { ModuleInstanceDescriptor instance; // Common Audio Weaver module instance structure INT32 exp; // number of guard bits of the reciprocal output. Default is Q9.23 format. } ModuleReciprocalFract32Class;
