Hiya i've just started this project, and i was wondering if someone could help me or give me some advice and point me in the right direction. This is what i've got to do. Using C programming write a progra capable of calculating a series of sample points that can be used to generate an arbitrarily specified waveform using one of two specified methods. Then ported to a 68HC11. The program should be simple menu drive structured program that allows the user to choose between two methods of defining a time- domain waveform. The program should calculate a table of values that can be written to a data file, then the data file should be used to generate the waveform in real time using the parallel port and a A/D converter. The user should be able to specify every aspect of the waveform - amplitude, frequency, harmonic content, pulse amplitudes and durations. y(t) = a |
