Circuits Signals and Systems

So I have a module to study for. Its called Circuits Signals and Systems. Its about electronics. Its cool stuff, we get to learn about symbols, about capacitors batteries, inverters, amplifiers and the list goes on. Its kinda fun, but often challenging as you have to solve some mathematical problem related to the circuits. Burt then you realize that no matter how complicated a circuit is, if you know some rules about basic components and the laws that relate to the properties associated with these components when they are being used together, then even very big circuits  don't seem daunting anymore. Ideally, you break the problem into smaller problems and solve.
  It doesn't stop there though. Signals and Systems, are very fascinating topics. One can understand how to build a system that can be used to model a control problem, like if an object was flying and you wanted stability how can you control its pitch more effectively- without human input - can this be automated?
 Well, Signals and Systems will say we can construct a dynamic model of this problem and solve for it. Often the analysis of telemetry like data is necessary and some equations from basic dynamic vibration theory is needed to do the job.
  Its an intriguing set of topics, and especially applicable today, due to the heavy reliance on computer electronics.  
  The mathematics of it can be complicated, especially when learning about Closed-Loop Transfer functions, and being able to assess the conditions necessary for this, and knowing what poles are.
  In order to assess a system for a certain condition, some important ideas need to be clarified first. I suppose this is quite nice in a way as you can simply check if the system meets the requirements and then based on this build a sound conclusion. So you know where to start, which is nice!
  So, I continue to learn about this, and then finals!!!
