How to get unfiltered data as o/p of band pass filter

[PSADSP]

Hello,

Im new to Labview and exploring it.

Im implementing a system wherein I need to use a LPF and a series of Band Pass Filter.

The filtered o/p of LPF acts as i/p to 1st BPF....

Later the UNFILTERED o/p of 1st BPF acts as i/p to 2nd BPF.

The problem im facing is: I cannot see any box in signal processing which gives the filtered and unfiltered data together in time domain.

Could you please help me with this asap....desperately in need of your help.

Thanks,

PSADAP

There is no direct tool for this, but there a workaround for your requirement.

Say if you're using a LPF (with cut off frequency, say 50 Hz), now to get blocked (UNFILTERED as per your terminology) signal, put a HPF (with cutoff frequency of 50 Hz).

See the block diagram
