Unformatted text preview: circuit. The NI Elvis is a better choice than the traditional equipment because rather than make the experiment a mundane set of instructions of data acquisition, it allows for more understanding as to why the particular measuring device is being used. It does seem to be producing slightly different results compared to the traditional equipment but stays within 4% deviation, hence rendering this issue obsolete. With respect to magnitude, a first order low pass filter attenuates high frequencies whereas a first order high pass filter attenuates low frequencies. A low pass filter could be used to block off high frequency random noise whereas a high pass filter could block off low frequency bass signals from transmitting to the tweeter. With respect to frequency, a low pass filter shifts its phase from 0 to -90 degrees whereas a high pass filter shifts its phase from 90 to 0 degrees....
