31. An important principle used in crystal radio design to transfer maximum power to the earphone is impedance matching . 32. I will check out impedance matching . 33. The Impedance Matching Room has a matching transformer to perform impedance matching between the transmitter and the antenna. 34. With this approach, the original specification for passband and stopband can be kept while simultaneously improving the impedance matching . 35. In some cases, improved impedance matching ( via careful enclosure design ) lets the speaker produce more acoustic power. 36. The original 4558 based circuit uses transistor buffers at both the input and the output, to improve impedance matching . 37. Similar to the impedance matching case, this can be improved by using multiple elements, resulting in a filter-like structure. 38. The data transfer is relatively slow, so transmission line issues such as impedance matching and line termination are ignored. 39. Normally, an impedance matching network matches the impedance of the antenna to the impedance of the transmission line feeding it. 40. :: According to the impedance matching article, stereo amplifiers actually use impedance bridging ( which is news to me ).
