Consider the circuit shown in the figure below:

The current I₀ is measured by using an ideal DC ammeter. If the diode D is ideal, then the value of the current that will be displaced by the ammeter will be _____ mA.

If given above is Fourier transform of signal x(t) and is Hilbert transform of signal x(t) then determine the plot of
