QPSK 调制与解调
数字调制技术一套的基础功能选择特定的调制方案。一般的基础功能是互相正交的。可以使用 "克施密特正交化" 过程派生的基础功能。一旦选择了基础功能,任何信号空间中的向量可以表示为基函数的线性组合。
在正交相移键控 (QPSK) 两个正弦波 (sin 和 cos) 作为基函数调制的。调制被通过不同相的基础功能,根据消息符号。在 QPSK,调制是基础,在那里有一个符号包含 2 位的象征。

dragonchip:作为一个示范的定时器的使用0,1,2,作为反例,T.
Dragonchip:一个演示如可使用Timer 0, 1, 2作为计数器的例子,This program counts pulses generated by Counter A using Timer 0, 1, 2,at the same time and toggle PA2, PA1 and PA3 respectively. Pulses from PA1
then feed into PB6(T2EX) to trigger Timer 2 interrupt to toggle PA4. The Crystal frequency is 8MHz.-Dragonchip : as a demonstration of the use Timer 0, 1, 2, as counter examples, This program counts pulses generated by Counte r A using Timer 0, 1, 2, at the same time and toggle PA2. PA1 and PA3 respectively. Pulses from PA1 then f eed into PB6 (T2EX) to trigger Timer 2 interrupt to toggle mouse. The Crystal frequency is 8MHz.
