Table 22: Cartesian - To -Polars - Safran CORTEX CRT Quantum User Manual

We notice that:

In the first term, the demodulated output is amplified when the discriminator delay is increased or when the
Cartesian-to-polar sampling frequency Fs is decreased,

The sinc term filters the output with a bandwidth which is increased when the Cartesian-to-polar sampling
frequency Fs is increased or when the discriminator delay is decreased.
There are the values of the Cartesian-to-polar sampling frequency Fs corresponding to the different Pre-
Detection filters:
