PD
(PHASE
DISTORTION)
SOUND
SOURCE
The CZ-3000
employs
a unique, CASIO
developed
PD (Phase
Distortion)
sound source
system. This
system is
capable of
producing a variety
of
wave forms by distorting
the
read
phase
angles of
sine and cosine
waves
that
are Written
in ROM,
The pattern ol the read
phase angle distortion
is determined by
the specification
of the DCO
(VCO of
analog syn-
thesizer)
WAVE FORM. The
magnitude
(modulation
depth)
of the read angle
distortion
corresponds
to the
momentary value
of the
DCW (VCF of
analog synthesizer)
envelope.

cosine wave
when a
co-
sine wave in ROM
is read with
a
linear phase angle. The
phase

read
at a cofisLmil speed

As shown
in Fig.
2,
the
phase
angle
read is distorted
rather
than
linear, and the output
co-
sine wave
takes on what
is close
to a saw-tooth
pattern.
What would
happen now if
we
further
increase
the phase angle
read speed from
through
tt
and decrease
it from
x through
2t?

the output co-
sine
wave is almost
a perfect
saw-tooth
pattern.
