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.

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
