Crossover Networks and Filters

  In this article, we will examine the fundamental components of any electric circuit - inductors (coils), capacitors (condensers), and resistors.       Inductance The property of a circuit to resist change in current by inducing a voltage in the opposite direction, or the magnitude of thereof, is called Inductance. It is the electromagnetic [...]
