- jononor 3y agoWhether it is signal of interest or not, if above the sampling rate it will be aliased down into lower frequencies. So all energy above the sampling rate should be removed to avoid this disturbance.
- iamcreasy 3y agoSo low pass filter is always mandatory? For example, in this RC car case - lets say we are sampling at 1Hz and the signal appears to be clean. But we still have to run a low pass filter of ensure the motor vibrations are removed?
