Note 1
The discriminator output peak-to-peak voltage is measured by operating the discriminator mixer with two separate inputs (ie as a mixer) A beat frequency
of 1 kHz is generated and this tone’s output swing is guaranteed to be at least 10 VPP When the mixer is configured as a discriminator with the limiter and a tank
circuit the guaranteed 10 VPP output translates to (10V (36180) e ) 200 mVPP demodulated output assuming at least 36 phase shift across the band of
interest from the tank circuit
