會...一定會爆....不過係爆棚個爆 .....呢件咪係兀型濾波豪華版 ...

The capacitor-input filter, also called pi filter due to its shape that looks like the Greek letter pi, is a type of electronic filter. Filter circuits are used to remove unwanted or undesired frequencies from a signal
A typical capacitor input filter consists of a filter capacitor C1, connected across the rectifier output, an inductor L, in series and another filter capacitor, C2, connected across the load, RL. A filter of this sort is designed for use at a particular frequency, generally fixed by the AC line frequency and rectifier configuration. When used in this service, filter performance is often characterized by its regulation and ripple.
The capacitor C1 offers low reactance to the AC component of the rectifier output while it offers infinite resistance to the DC component. As a result the capacitor shunts an appreciable amount of the AC component while the DC component continues its journey to the inductor L
The inductor L offers high reactance to the AC component but it offers almost zero resistance to the DC component. As a result the DC component flows through the inductor while the AC component is blocked.
The capacitor C2 bypasses the AC component which the inductor had failed to block. As a result only the DC component appears across the load RL.
The capacitor-input filter, also called pi filter due to its shape that looks like the Greek...

電容加線圈？
好似 PF30 個類？

其實scheme就各家都差不多...只係料同走位有分別
比我試到個正濾斗濾組合。

小弟不材, 即係乜野來?!望高人明示{:6_122:}
唸住點較？

最簡單方法, 將條鍍銀訊號線變返做紫銅RCA線, 等D聲暖返少少, 雖然空間感無鍍銀咁強, 但應該會多返少少人味, 但條線借左俾老友玩, 要等下先{:6_126:}

但係鍍銀線本身都幾難會暖吓喎！{:6_136:}
