As Frank mentioned, it does, but "interpolation" in itself is a heavily
overloaded word. Consider linear interpolation: it is, it is done, but
during upsampling, sine wave at Nyquist transforms into triangular and
sub-Nyquist sines are high-freq distorted, too... :( Interpolation is the
field, where the question of "how" is, IMO, of even greater importance than
that of "if".
