Question:

Fig. 4.32 illustrates the simplest ripple filter. A voltage V = V o (l + cos wt) is fed to the left input. Find:
(a) The output voltage V' (t);
(b) The magnitude of the product R at which the output amplitude of alternating voltage component is η = 7.0 times less than the direct voltage component, if w = 314 s€“l.
