A signal x(t) can be expressed as follow: x(t) = 2 rect (t/2) Classify x(t) as energy signal or power signal and calculate the value.

2.7 Classify these signals into energy-type signals, power-type signals, and signals that are neither energy-type nor power-type. For energy-type and power-type signals, find the energy or the power content of the signal. 1. x(t) = (÷)'u( 2. x(t) = ej(}t+) %3D 3. x(t) = 7(-1)' for t> 0 and else 0 4. x(t) = e³'u(t)
