$1)$ For the schematic shown below: $9)$desions an $\backslash ($ A c $/$ D c $\backslash )$ Voltage regulator using a fullbridge rectifier transformen $\backslash (($N$=7)\backslash )$ so that the output at the load is $\backslash (5$ V $\backslash )$

b$)$ Determine the puaktapalk ripple voltuge $(\backslash ($ V$\_\{$p p$\}\backslash )\text{'})$ at the capacitance and the repuired copacitan $4($C$)$ so that the peak$-$to$-$peak ripple at the output just comply with the indus triul standard seen in class, and the lood whent is maximum
