Hello.
To achieve maximum power transfer, the impedance matching is important for both a lumped electrical network or a circuit with a transmission line. However, for a signal reflection, is the matching also important for the lumped network? Let's see the attached figure.
Let's assume ZS ≠ Z0 ≠ ZL. We know that a signal incident on the ZL from Z0 is reflected at their interface. The reflected signal goes toward ZS and is reflected again at the interface of ZS and Z0. So far so good. But, what about when the signal transfers from ZS to Z0 at the first time? Is there also a reflection at the interface and the reflected signal bounces back and forth between ZS and Z0 ?
This is the question I almost never seen from the textbook or articles so I didn't get it clarified yet. Please help me to solve this.
