What Does the Heaviside Step Function Formula Represent?

[teng125]

f(x) = <x-a>^1 - <x-2a>^1 - a<x-3a>^0

this is a diagram of heaviside step function.does anybody has any website regarding this materials so that i can get to learn such as why is it power of one and power of zero plssss

thanx very much

I'm not sure exactly what your equation represents, but here are a few links that have infomation on the heaviside step function

What does "< >" mean?? It's clearly not just like parentheses since in that case you don't have a Heaviside function.

Are you saying that by $<x-a>$ you mean a step function which switches on at $x = a$ (and stays so for $x \geq a$)?
