In So you think you understand transmission lines, I offered a seeming paradox about a property of transmission lines.If you look at the input impedance of a uniform transmission line, open at the far ...

Using circuit simulating software like SPICE can be a powerful tool for modeling the behavior of a circuit in the real world. On the other hand, it’s not always necessary to have all of the f… ...

Series-parallel circuit. The Figure at right shows three impedances; two are connected in parallel and then connected in series with a third impedance. Each impedance can be a pure resistance, a pure ...

An LC circuit often called a “pi-network” is commonly used to match the impedance of a transmitter's load (an antenna) to something more suitable for the transmitter's output amplifier. That output ...

For simplicity, the circuit is normalized to a 1 Hz resonant frequency and a characteristic impedance of 1 Ω, defined by the equal values of L1 and C1. Figure 1 At resonance, the input resistance ...
