Unformatted text preview: f ( t ), we need to change f ( t ) into linear combinations of step functions u a ( t ). Here u a ( t ) = u ( t-a ) = ‰ 0 if t < a 1 if t ≥ a and u ( t ) = ‰ 0 if t < 1 if t ≥ is called Heaviside function or unit step function . We have graphed some step functions, Figure 1. Step Functions...
