Title: Improvements in and relating to time-frequency analysis
Inventor: ALEKSANDR RUSINOV
IPC: H01J49/02
Filed: 2020-05-27
Abstract: Apparatus and method for processing an image-charge/current signal for an ions undergoing oscillatory motion within an ion analyser apparatus. The method comprises obtaining a recording of the image-charge/current signal, 20a, 20b in the time domain. Using a processing unit, a value for the period T of a periodic signal component is determined within the recorded signal. The recorded signal is segmented into a number of successive time segments of duration corresponding to the period T. These time segments are then co-registered in a first time dimension t1 defining the period T. The co-registered time segments are then separated along a second time dimension t2 transverse to the first time dimension t1. This generates a stack of time segments collectively defining a 2-dimensional function. The 2D function varies both across the stack in the first time dimension and along the stack in the second time dimension.
