Requirements for Improved Resolution

The word “resolution” is often assumed to refer to the specific case of temporal resolution. In that regard, Kallweit<br>& Wood (1982) observed that when two octaves of bandwidth are present, the limit of temporal resolution can be<br>expressed as 1/(1.4 x FMAX ). However, equally important is the issue of spatial resolution. One of the methods<br>proposed by Berkhout (1984) for quantifying spatial resolution is via the use of the “spatial wavelet”. Such wavelets<br>demonstrate that better temporal resolution leads to better spatial resolution. A key point in this paper, though, is that<br>this relationship works the other way too. That is, better spatial resolution leads to better temporal resolution.
