Step response to an impulse response

AI Thread Summary
The discussion revolves around finding the step response of an LTIC system with a specified impulse response, h(t) = u(t) - u(t-2). The user initially struggles with the integration process needed to derive the step response, which involves integrating h(t) over the range from -∞ to t. Despite the challenge, the user eventually resolves the issue independently. The conversation highlights the importance of understanding the relationship between impulse and step responses in system analysis. The user expresses gratitude for the eventual clarity achieved in solving the problem.

Hi all,

I'm having a lot of trouble understanding this step response:

Problem statement:

Consider an LTIC system with impulse response given by: h(t) = u(t) - u(t-2)

Sketch the step response s(t).


I've already sketched h(t)...but,
I know that the step response is found by integrating h(t) with respect to tau over the range -∞ to t. I know this is not hard, but for some reason I'm just having trouble figuring out what to do, and my text doesn't cover the step response at all (probably because it's so easy).

Any help if how to find the step response would be appreciated. Thanks

Well, I figured out on my own.
 
Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
