Determine which statements are true or false and justify your answer using frequency domain analysis:
a) The signal x(t) = u(t + To) - u(t -To) can undergo impulse-train sampling without aliasing provided that the sampling period is Ts < 2To
b) The signal x(t) with Fourier transform X(j ) = u( + o) - u( - o) can undergo impulse-train sampling without aliasing provided that the sampling period is Ts < /o
c) The signal x(t) with Fourier transform X(j ) = u() - u( - o) can undergo impulse-train sampling without aliasing provided that the sampling period is Ts< 2/o.
In all of these problems, please sketch the signal in time and frequency domain, and justify your answer based on the graphs.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
