High Pass Filter for low frequency

[chadp]

I need to run several analog signals through a high pass filter, targetting a very low frequency ( <1Hz). My current plan requires a lot of memory to accomplish this. Are there any functions in OSCAT that can do this without requiring a lot of memory to hold data samples?  Or, is there a good way to down-sample the signal without compromising low frequency resolution?

I am running out of free memory and I still have more functions to add.
