参照栈类模板的例子编写一个队列类模板Class <T> Queue，私有成员包括：队首指针Front，队尾指针Tail，队列容积max。实现：构造函数Queue，复制构造函数Queue，析构函数~Queue，入队函数In，出队函数Out（每次出队，后面的元素自动前移一位），判队列空函数Empty。并分别用队列类模板定义int和double对象，通过实例调用各个成员函数。

Software Radio (SR) is one of the most important emerging technologies for the future of wireless communication services. By moving radio functionality into software, it promises to give flexible radio systems that are multi-service, multi- standard, multi-band, reconfigurable and reprogrammable by software. Today’s radios are matched to a particular Class of signals that are well defined bytheircarrierfrequencies,modulationformatsandbandwidths.Aradiotransmitter today can only up convert signals with well-defined bandwidths over defined center frequencies, while, on the other side of the communication chain, a radio receiver can only down convert well-defined signal bandwidths, transmitted over specified carrier frequencies.

This design uses Common-Emitter Amplifier (Class A) with 2N3904 Bipolar Junction Transistor. Use “Voltage Divider Biasing” to reduce the effects of varying β (= ic / ib) (by holding the Base voltage constant) Base Voltage (Vb) = Vcc * [R2 / (R1 + R2)] Use Coupling Capacitors to separate the AC signals from the DC biasing voltage (which only pass AC signals and block any DC component). Use Bypass Capacitor to maintain the Q-point stability. To determine the value of each component, first set Q-point close to the center position of the load line. (RL is the resistance of the speaker.)

EMC的分类及标准：EMC（E1ectromagnetic Compatibility）是电磁兼容，它包括EMI（电磁骚扰）和EMS（电磁抗骚扰）。EMC定义为：设备或系统在其电磁环境中能正常工作且不对该环境中的任何设备的任何事物构成不能承受的电磁骚扰的能力。EMC整的称呼为电磁兼容。EMP是指电磁脉冲。EMC=EMI+EMS EMI：电磁干扰EMS：电磁相容性（免疫力）EMI 可分为传导Conduction及辐射Radiation两部分，Conduction规范一般可分为：FCC Part 15J Class B；CISPR 22（EN55022，EN61000-3-2，EN61000-3-3）Class B；国标IT类（GB9254，GB17625）和AV类（GB13837，GB17625）。FCC测试频率在450K-30MHz，CISPR22测试频率在150K--30MHz，Conduction可以用频谱分析仪测试，Radiation 则必须到专门的实验室测试。
