SUMMARY
The discussion focuses on computing the convolution of two functions, f(t) = cos(t) and g(t) = U2(t), where U2(t) represents a Heaviside function with a discontinuity at t = 2. The convolution is defined as f*g = ∫f(t-u)g(u)du, leading to the integral f*g = ∫cos(t-u)U2(u)du. Participants clarify that the limits of integration must be adjusted to account for the Heaviside function, resulting in the integral being evaluated from 2 to t, as U2(u) equals 1 for u ≥ 2.
