Low-pass filter 低通滤波器电路: R1 = R2 = 24 K C1 = 2 * C2 = 940 pF, C2 = 470 pF 6 dB High-cut Freq = 10 KHz......
一、设计及制作 由于普通家庭室.内空间不够宽敞,要求音箱做得尽可能小巧一些,摆放在室内不致引人注意。然而,音箱的效率no与箱体容积VB和低频-3d8滚降点f3有以下关系: no=kn·f3......
该电路特别适合FU50胆,电路原理见附图。它可延时2分55秒。乍看它和普通延时电路没有什么大的区别,但它多了R1和D5组成的泄放电路,区别就在于此。当关机时电路断电,电解电容C2上所充的电压通过二极管D5加到电源正极,......
