그림의 파형을 단위 함수 (unit step function) $f(t)$ 로 표시하면?

Subscribe to see the correct answer.

$f(t) = u(t-T) -2 u(t-2T) + 2 u(t-3T)$

$f(t) = u(t) - u(t-T) + u(t-2T)-u(t-3T)$

$f(t) = u(t-T) - u(t-2T) + u(t-3T)$

$f(t) = u(t) - 2u(t-T) + 2u(t-2T)-u(t-3T)$

Solution

$f(t) = u(t) - 2u(t-T)+2u(t-2T)-u(t-3T)$
