Hi all, I posted previously and I think my description may have been poor and misleading as to what I was after so I thought I'd repost and try be more accurate.
I have an automotive wheel speed sensor that that was not intended to be used with the control unit in the vehicle that is a hall effect sensor that produces a square wave signal that alternates high and low 50%, it measures 0.6v when low and 1.3v when high.
I want to add some form of interface between the hall effect sensor and the control module to make this signal look like the signal that was produced by the original inductive sensor that produced an A/C sine wave signal that measures around 5v peak to peak at 150Hz and needs to read up to around 900Hz, obviously the amplitude increases with increased rpm but I don't think this will be necessary. Below is a representation of what the signals look like at 150Hz. i hope I've done a better job of explaining this time.
