| 31. | It had a characteristic impedance of 50 ?, and was adopted for use in the emerging broadcast industry.
|
| 32. | This is directly analogous to the definition of characteristic impedance as the input impedance of an infinitely long line.
|
| 33. | Given its a high frequency system where matching characteristic impedance is pretty vital this means the voltage has to split too.
|
| 34. | An even faster transition into the stop-band and an even more constant characteristic impedance in the pass-band.
|
| 35. | The characteristic impedance of a transmission line is the ratio of the voltage and current of a wave travelling along the line.
|
| 36. | A wave is partly reflected when a transmission line is terminated with other than a pure resistance equal to its characteristic impedance.
|
| 37. | A load that matches the characteristic impedance ( defined below ) will completely absorb the wave and the energy associated with it.
|
| 38. | These two definitions are not exactly equivalent because the characteristic impedance at the receiver may be different from that at the source.
|
| 39. | On the other hand, at high frequency in the MHz region, the characteristic impedance flattens out to something almost constant.
|
| 40. | This is because the LAN data is in a higher frequency band where the characteristic impedance is substantially flat and mostly resistive.
