Digital Filtering: How to Resources

[brmech]

I'm struggling through reference papers on digital filtering. Can anyone recommend introductory information resources on this subject?

My application is to filter out noise from strain gauge data. I'm using a NI data acquisition pc card, LabView 5.1 Basic version, and MathCad 8 Professional.

I could use an analog filter, but I want to have more signal conditioning flexibility by using digital filtering.

I'd recommend "Frequency Analysis" by Bruel&Kjaer, but if that is too complex to start with then Hewlett Packard has a nice booklet #243 "Fundamentals of Signal Analysis".

Cheers
