[TenTec] TenTec Digest, Vol 163, Issue 18

[Carl Moreschi]

Bandwidth is traded for latency.  The sharper the bandwidth, the more 
processing time that is taken, thus increasing latency.  Also slop 
factor on the DSP filters affects latency.  The steeper the filter 
skirts, the more processing time is needed thus also increasing latency.

Dynamic range is all about the maximum voltage range that the DSP front 
end can handle before it goes into saturation.
