Subject: Digital Frequency Discriminator - calibration 

 One more thing ... we can calibrate the output of the LP filter to give a result in Hz with the following calibration:

LP_OUT = -1/(2*dt)*(LP_IN -1), where dt is 1/16384, the delay time of the delayed path.

Therefore LP_OUT = -8192*(LP_IN-1).
