This block takes in a complex stream and outputs each complex value's arg (a.k.a. arctan, see [1]). The output is a float.
Parameters
None
Mathematical Description
Assuming an input of , then the output of this block corresponds to .
![{\displaystyle c[n]=r[n]+i[n]j}](https://en.wikipedia.org/api/rest_v1/media/math/render/svg/eb4f3946182c5f085ecc124598ff804b584016c6)

Example Flowgraph
This is a frequency demodulator. The blocks from the output of the FFT Low Pass Filter to the output of the Multiply Const block is equal to the Quadrature Demod block.
