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

Subscribe to see the correct answer.
1

f(t)=u(t)u(tT)+u(t2T)u(t3T)f(t) = u(t) - u(t-T) + u(t-2T)-u(t-3T)

2

f(t)=u(t)2u(tT)+2u(t2T)u(t3T)f(t) = u(t) - 2u(t-T) + 2u(t-2T)-u(t-3T)

3

f(t)=u(tT)u(t2T)+u(t3T)f(t) = u(t-T) - u(t-2T) + u(t-3T)

4

f(t)=u(tT)2u(t2T)+2u(t3T)f(t) = u(t-T) -2 u(t-2T) + 2 u(t-3T)
