Digital filtering

[NeedToKnow]

How to add a digital BPF (FIR/IIR) to the sampled data?

Hi,

The front end of a real DSP must be made up of a low pass filter, for example a Butterworth LP of the fourth order, followed by the sample and hold system and then by the ADC. The sampling rate must comply with the Shannon sampling theorem (don't  take a sample rate at your leisure). 

[NeedToKnow]

How about FIR filter?

Consult the Help system of Mathcad, I'm sure there are some nice examples.

But they may be in an e-book called 'signal processing', which should also be accessible through the 'Help' menu..

Success!
