Generating a Binary Signal
显示 更早的评论
How do I generate a binary signal and export the file as a audio file (.wav,.mp3,etc)?
EDIT:
I want to generate a pulse that has high and lows. I would also like to be able to control the relative proximities of the highs and lows and store this pulse as a .wav file. So when I play this pulse and analyze it with an oscilloscope I expect to see something like this http://upload.wikimedia.org/wikipedia/commons/5/55/NRZcode.png with the troughs at 0 volts

This question is too general to be answered efficiently. What exactly do you want and can you imagine any method to create a non-binary signal on a computer?

You cannot control the relative proximity of the highs and lows in a .wav file, as .wav files are fixed frequency.
If fixed frequency is acceptable, then just generate your data as a column vector and use wavwrite() on it.
