Convolution of the step function, three times

Click For Summary
SUMMARY

The convolution of the step function \( u(t) \) performed three times results in \( \frac{1}{2} t^2 u(t) \). The initial convolution \( u(t) * u(t) \) simplifies to \( t u(t) \). Subsequently, convolving \( t u(t) \) with \( u(t) \) leads to the integral \( \int_0^t \tau d\tau \), confirming the final result of \( \frac{1}{2} t^2 u(t) \) as accurate.

PREREQUISITES
  • Understanding of convolution operations in signal processing
  • Familiarity with the unit step function \( u(t) \)

Homework Statement



u(t) * u(t) * u(t)

* indicates convolution

Homework Equations



i know u(t) * u(t) = t u(t)

The Attempt at a Solution



so (t u(t)) * u(t) = \int \tau d \tau limits of integration are 0 to t
so the answer is 1/2 t^2 u(t)?
