Description

Conjugates the elements of a complex data vector.

-

The pSrc points to the source data and pDst points to the where the result should be written. numSamples specifies the number of complex samples and the data in each array is stored in an interleaved fashion (real, imag, real, imag, ...). Each array has a total of 2*numSamples values. The underlying algorithm is used:

The pSrc points to the source data and pDst points to the destination data where the result should be written. numSamples specifies the number of complex samples and the data in each array is stored in an interleaved fashion (real, imag, real, imag, ...). Each array has a total of 2*numSamples values.

The underlying algorithm is used: 

-for(n=0; n<numSamples; n++) {
-    pDst[(2*n)+0)] = pSrc[(2*n)+0];     // real part
-    pDst[(2*n)+1)] = -pSrc[(2*n)+1];    // imag part
+for (n = 0; n < numSamples; n++) {
+    pDst[(2*n)  ] =  pSrc[(2*n)  ];    // real part
+    pDst[(2*n)+1] = -pSrc[(2*n)+1];    // imag part
 }

There are separate functions for floating-point, Q15, and Q31 data types.

Scaling and Overflow Behavior:

-
The function uses saturating arithmetic. The Q15 value -1 (0x8000) will be saturated to the maximum allowable positive value 0x7FFF.
