Consider the second-order differencing filter described by the input-output relationship y[n] = x[n+1] – 2x[n] + x[n – 1] I) Show that the complex frequency response H(ej") is actually real-valued. What is the output of the filter when the input is x[n] = cos(@n) (for all n n)? For what %3D value(s) of w is the output zero for all n?

Question A
Electric machines/ I need to choose the correct answer with a brief explanation for it.
In the distribution transformer;In the transformer used for the distribution of electricity to the houses, 3.3 kilovolts enters and 400 volts come out. When we make the phase-neutral calculation, that is, when we divide it by √3, we get 230 volts and 220 volts coming to the sockets. Where does the remaining 10 volts go? (Can you explain with figure) is this about 30 degree phase shift?
