Abstract: The spectrum analysis of unsteady signal is always difficult. A new method of time-frequency
analysis on unsteady signal, short time MEM (STMEM) spectrum matrix is described in this paper. It
was anticipated to have special effect on time-frequency analysis.
Keywords: short time, MEM, spectrum matrix analysis, unsteady signal, time-frequency analysis.
