Before two weeks, the friend helped me look for to build five of 441 95 into new car stage, paid silver, look at new bought car station, new! 35W! I fondle admiringly, come home to hook up with a young plant rapidly, receive on my switch power source Posted at 08-08-11 by Admin views(29)
Half semmetry brace up child with line of make a present of match General reception equipment (like the television) its input characteristic impedance to be 75 (lopsided pattern) or 300 balance type, half semmetry brace up child output is: M blows?5 Posted at 08-08-11 by Admin views(27)
1, group when delay lack fidelity Group when delay lack fidelity belong to a kind of linear lack fidelity, it basically is introduced by filter. This kind lack fidelity will cause undesirable effect to TV picture quality. If be in program of transmis Posted at 08-08-11 by Admin views(24)
Graph 1 it is half semmetry brace up child cable deserves to accept a plan, because half brace up child The input impedance that looked at 2 o'clock from AB is 73 , two brace up child have symmetry rightly, reason A, B was 73/2=36.5 respectively to t Posted at 08-08-11 by Admin views(20)
