一个fft的简单实现仿真的例程，画出频谱，观察信号的频谱。(An fft simple simulation routine to draw the spectrum, observed spectrum of the signal.)

说明：  The concerns for environment due the ever increasing use of fossil fuels and rapid depletion of this resource have led to the development of alternative source of energy such as solar energy. This paper proposes that how to increase the efficiency of a solar PV energy system by the advancement in conventional DC to DC Boost converter. This paper also proposes the study of open loop systems with elevated step-up conversion and step amplify in input voltage. An improved DC to DC boost converter is modeled and simulated using MATLAB. This improved boost converter provides the constant output voltage irrespective of the variable output voltage. The simulation results of this system are presented and compared. The result of the improved boost converter is also compared with the conventional boost converter. This result verifies that with the minimum number of components the proposed improved boost converter system has the advantages of high efficiency.
