Extracted text: the value of a. 2.3-1 In Fig. P2.3-1, the signal g1 (t) = g(-1). Express signals g2(t), 8 3(1), 84(t), and 8 5(1) in terms of signals g (t), g1 (t), and theirtime-shifted, time-scaled, or time-inverted versions. For instance, 82(t) = 8 (1 – T)+ 81(1 – T) for some suitable value of T. Similarly, both g3 (t) and g4(t) can be expressed as g(t-T)+g(t–T) forsome suitable value of T. In addition, g5(t) can be expressed as g(t) time-shifted, time-scaled, and then multiplied by a constant. Figure P.2.3-1 g(t) 82(1) 2 1.5 84(1) -1 2 2.
