The government of a small but important country has decided that the alphabet needs to be streamlined and reordered. Uppercase letters will be eliminated. They will issue a royal decree in the form of a String of B and A characters. The first character in the decree specifies whether a must come ( B )Before b in the new alphabet or ( A )After b . The second character determines the relative placement of b and c , etc. So, for example, "BAA" means that a must come Before b , b must come After c , and c must come After d . Any letters beyond these requirements are to be excluded, so if the decree specifies k comparisons then the new alphabet will contain the first k+1 lowercase letters of the current alphabet. Create a class Alphabet that contains the method choices that takes the decree as input and returns the number of possible new alphabets that conform to the decree. If more than 1,000,000,000 are possible, return -1. Definition

Robotics TOOLBOX The Toolbox provides many functions that are useful in robotics including such things as kinematics, dynamics, and trajectory generation. The Toolbox is useful for simulation as well as analyzing results from experiments with real robots. Have fun with the toolbox. It is self-explanatory and very (robotics) user friendly...see the robot.pdf

Use the fast Fourier transform function fft to analyse following signal. Plot the original signal, and the magnitude of its spectrum linearly and logarithmically. Apply Hamming window to reduce the leakage. . The hamming window can be coded in Matlab as for n=1:N hamming(n)=0.54+0.46*cos((2*n-N+1)*pi/N); end; where N is the data length in the FFT.

開關在電路中起接通信號或斷開信號的作用。最常見的可控開關是繼電器,當給驅動繼電器的驅動電路加高電平或低電平時,繼電器就吸合或釋放,其觸點接通或斷開電路。CMOS模擬開關是一種可控開關,它不象繼電器那樣可以用在大電流、高電壓場合,只適于處理幅度不超過其工作電壓、電流較小的模擬或數字信號。 一、常用CMOS模擬開關引腳功能和工作原理 1.四雙向模擬開關CD4066 CD4066 的引腳功能如圖1所示。每個封裝內部有4個獨立的模擬開關,每個模擬開關有輸入、輸出、控制三個端子,其中輸入端和輸出端可互換。當控制端加高電平時,開關導通;當控制端加低電平時開關截止。模擬開關導通時,導通電阻為幾十歐姆;模擬開關截止時,呈現很高的阻抗,可以看成為開路。模擬開關可傳輸數字信號和模擬信號,可傳輸的模擬信號的上限頻率為40MHz。各開關間的串擾很小,典型值為-50dB。
