calculation
#3:
Maximum
number
of
steps
is
equal
to
the
minimum
of
1023
or:
1100
000
000 Hz - 500 000 000 Hz
1=
400 000 000
1
Hz
Since
1023
is
less
than
400
000
000,
the
maXlInum
number
of
steps
is 1023.
Minimum
number
of
steps
is
equal
to
the
minimum
of:
[INTEGER

1=

Hz
Since 2
is
less
than
400000000,
the
minimum
value
of
steps
is
2.
Therefore,
it
should
be possible
to
select
100
steps
SJ[l
e
that
value
is
between
the
minimum

(2)
and
