算24点的程序,Matlab下使用,比赛主办方提供的参考资料,完全可以使用.(Count 24 point program, Matlab is used, the game organizers to provide reference materials can be used.)

设计一个按照时间抽取的基2快速傅里叶变换（基2FFT-DIT）。输入倒位序，输出自然顺序。(Design is taken in accordance with the time radix-2 fast Fourier transform the (base 2FFT-DIT). Enter the inversion sequence, the output of the natural order.)

脉冲宽度调制（PWM）是英文“Pulse Width Modulation”的缩写，简称脉宽调制。它是利用微处理器的数字输出来对模拟电路进行控制的一种非常有效的技术，广泛应用于测量，通信，功率控制与变换等许多领域。一种模拟控制方式，根据相应载荷的变化来调制晶体管栅极或基极的偏置，来实现开关稳压电源输出晶 体管或晶体管导通时间的改变，这种方式能使电源的输出电压在工作条件变化时保持恒定。　　脉冲宽 (Pulse width modulation (PWM) is the English " Pulse Width Modulation" acronym, or pulse width modulation. It is the use of the microprocessor to the digital output of analog circuits for the control of a very effective technology, widely used in measurement, communications, power control and many other fields with the transformation. An analog control means, in accordance with the corresponding changes in load modulation transistor gate or base bias, switching power supply to achieve the output transistors or transistor on-time changes in power in this way can the output voltage in the workplace conditions of constant change.

temperature data logger-The temperature data logger is a device to read temperature and store persistent temperature and corresponding timestamp data into Flash memory. The collection of temperature data can be retrieved, and analyzed after being logged. The temperature data logger is commonly used for monitoring environmental data and shipments of temperature sensitive products such as foods, pharmaceuticals, and some chemicals. In particular, temperature data logger can operate as a stand-alone device and put in a variety of locations including office, laboratory or geographical location such as mountains, deserts,… and in manufacturing line in industry to collect temperature data over a defined period of time. It is also small enough and portable to be integrated with shipping container or directly attached to products which can be degraded due to exposure to temperature extremes to monitor their temperature
