| 摘要 |
A method of mass spectrometry is disclosed comprising digitising a signal output from a detector to provide a first digitised signal. A finite impulse response ("FIR") filter, a digital filter or an echo cancellation filter is applied to the first digitised signal in order to reduce the effect of baseline perturbations, echoes or ringing effects. Alternatively, an analogue signal output from a detector is passed to one or more first power splitters or dividers, wherein one or more first transmission lines are attached to one or more ports of one more said first power splitters or dividers in order to reduce the effect of baseline perturbations, echoes or ringing effects. |
