where Full Scale VPK =0.5 V.
The pulse metering oscillator has a volume envelope
(linear ramp) on the on/off transitions of the oscillator.
The ramp is controlled by the value entered into the
PMRAMP RAM address, and the sinusoidal generator
output is multiplied by this volume before being sent to
the
pulse
metering
DAC.
The
volume
value
is
incremented by the value in PMRAMP at an 8 kHz rate.
The volume ramps from 0 to 7FFF in increments of
PMRAMP, thus allowing the value of PMRAMP to set
the slope of the ramp. The clip detector stops the ramp
once the signal seen at the transmit path exceeds the
amplitude threshold set by PMAMPTH, thus providing
an automatic gain control (AGC) function to prevent the
audio signal from clipping. When the pulse metering
signal is turned off, the volume ramps down to 0 by
decrementing according to the value of PMRAMP.
Figure 24 illustrates the functional blocks involved in
pulse-metering generation, and Table 28 presents the
register and RAM locations required that must be set to
generate pulse-metering signals.
