Problem 1. (B01) Characterize the systems below, i.e. see what properties they have or do not have. The properties you should be investigate for are (i) homogeneity, (ii) superposition property, (iii) linearity, (iv) time-invariance, (v) causality, (vi) memoryless property and (vii) Bounded- Input/Bounded-Output (BIBO) stability. Assume that their inputs r is an arbitrary, complex- valued signal. T1 {r(t)} = |r(t)I (la)
