| Applications
of electronic interpolation
exist, for instance, in conjunction with incremental
encoders for position or angle measurement. The way in
which the signals are generated is irrelevant, so that
both optical and magnetic encoders can be used.
The main
characteristics of
electronic interpolation are the interpolation rate (i.e.
the number of discrete angular steps of a sine period),
the maximum input frequency and the type of output
signals. Apart from these parameters, electronic
interpolation systems are also discriminated by the way
in which amplitude, offset and phase errors of the input
signals are treated.
