This paper addresses the problem of additive and multiplicative abrupt jump detection. Two
detection algorithms based on the continuous wavelet transform are studied. Additive and
multiplicative jumps are compared in the time-scale plane. Considering non-zero mean
signals, we show that the same wavelet based algorithms can be used for the detection of
additive and multiplicative jumps. However, an analysis of the variance in the time-scale
plane allows us to distinguish these two kinds of jump.
