师兄去笔试，顺便摘了几个问答题：
1。what is computer graphics card? what is its function? what are the interface of graphics card?
2。what is graphics processing chipset? what is its function and usage on graphics card?
3。pls give the concept of the crosstalk between the signals the occurence condition,the behavior and the hard to the circuit design?
4。bypass capacitors are used to stablize reference voltage, we may use two bypass caps with different capacity , such as 0.1uf and 0.001uf ,what are the main functions of the two respectively?
5。bypass capacitors should be placed near reference voltage TTL and ECL logic circuit ,you will place them near GND or power and what is it when using CMOS device?
