P$7\mathrm{.}29.$ Several basic procedures using the Smith chart. For a transmission line or cnatacteristic impedance $50,$ terminated by a load impedance $(100+j50),$ find the following quantities by using the Smith chart: $($a$)$ reflection coefficient at the load; $($b$)$ SWR on the line; $($c$)$ the distance of the first voltage minimum of the standing$-$wave pattern from the load; $($d$)$ the line impedance at $d=0\mathrm{.}15$; $($e$)$ the line admittance at $d=0\mathrm{.}15$; and $($f$)$ the location nearest to the load at which the real part of the line admittance is equal to the line characteristic admittance.
