2. Any AC coupling at the receive input will transform any step in the voltage at the discriminator output to a
slowly decaying pulse which can confuse the modem's level measuring circuits. As illustrated in Figure 25
below, the time for this step to decay to 37% of its original value is 'RC' where:

Figure 25: Decay Time - AC Coupling
In general, it is best to DC couple the receiver discriminator to the modem and ensure that any AC coupling to
the transmitter's frequency modulator has a -3dB cut-off frequency of no higher than 5Hz for 4800
symbols/sec (9600bps).
