You are a summer intern at Acme Engineering Technology. You are given the task of working with a "black box" system $($called H$)$ designed by a colleague. Your colleague who designed H tells you that the input$-$output relationship is given by:

$($t$)=2($t$)*$ h$($t$)$

where r$($t$)$ is the input and y$($t$)$ is the output and h$($t$)$ is a function that is not specified.

TRUE or FALSE? H is definitely linear time$-$invariant?
