For each system shown below, find the following: $[$Section: $7\mathrm{.}6]$

$($a$)$ The system type

$($b$)$ The appropriate static error constant

$($c$)$ The input waveform to yield a constant error

$($d$)$ The steady$-$state error for a unit input of the waveform found in Part $($c$)$

$($e$)$ The steady$-$state value of the actuating signal.
