Linear Interpolation
Linear interpolation works by effectively drawing a straight line
between two neighboring samples and returning the appropriate point
along that line.
More specifically, let
be a number between 0 and 1 which
represents how far we want to interpolate a signal
between time
and time
. Then we can define the linearly interpolated
value
as follows:

(5.1) 
For
, we get exactly
, and for
, we get exactly
. In between,
the interpolation error
is nonzero,
except when
happens to be a linear function between
and
.
