The rectangular pulse function, denoted as $f(t)$, is defined piecewise. It takes the value 1 when the absolute value of $t$ is less than or equal to 1 (i.e., $|t| \le 1$), and it takes the value 0 for all other values of $t$ (i.e., $|t| > 1$).

Conditions: $t$ is a real number.; The function is defined on the entire real line.
