thanks for helping me solve this problem...
In EEG signals analysis , 16Hz frequency information is highly useful for determining the alertness of any person. The frequency spectrum characteristics of EEG signals can be seen from Fast Fourier Transform . Now , write a program in PIC 18 for the following conditions :
a) If the EEG frequency response of the subject shows a value above 16Hz means, send a ASCII letter Y to store it in memory location 0X11, and a red Led will be turned ON at PORTD,0.
b) If suppose , the frequency response value is less than 16Hz means, send a ASCII letter N to store it in that memory location (i.e. 0X11), and agreen LED will be turned ON at PORTD,1 to represent normal condition of the signal.
