For the rectifier circuit above, $$ is a sinusoidal source with an amplitude of $127$ V and a

frequency of $10$Hz$.$ NOTE the change in frequency, it is not $60$Hz$.$ The transformer is an ideal $10$:$1$ step down transformer. The diode is on when it has a forward voltage drop of $0\mathrm{.}7$ V across it$.$

a$)(4$ points$)$ If the capacitor is not present, what are the maximum and minimum voltages at the

output, $.$

b$)(6$ points$)$ Choose a capacitance value such that the voltage at the output drops by $5\%$ of the peak output voltage over the period of the input signal.
