If the discriminator is to produce an output that is distortion free, it
must operate on the linear portion of the characteristic curve. The linear portion
of this curve extends approximately from 5.96 MHz to 6.04 MHz, or for 0.08 MHz.
This is equal to 80 kHz.

V1 and V2 form a series-connected voltage divider.
Since current flows
one way, as shown in figure 141, the output will be a constant negative dc.
