Summary
Gnu Radio Companion equivalent flowgraph of the "Quadrature Demod" block. This is a polar discriminator circuit. The input complex samples are split. One sample is sent to a Multiply block, while the second set are delayed and conjugated before being fed into the Multiply block. The output of the Multiply block will also be complex samples, except they are now the phase difference between consecutive samples. The Complex to Arg block calculates the actual phase, in radians, for each of these complex samples. The Multiply Const block provides the "Gain" value as in the Quadrature Demod block.
