i kind of hoped that tabread4 would do some kind of interpolation<br>which might magically stop aliasing..<br></blockquote></div><br>
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".<br>
