Please be kind, its my first post!
I am trying to remove an +8 volt bias from a pulsed DC signal. The signal has a peak pulse of 60 volts and ranges from 8 hz to 70hz. I need to bring the bias as close to 0 volts as possible, and have an output trigger of at least 5 volt. Power supply voltage is 12 to 15 volt.
I tried using resistors to lower the voltage but I compressed the pulse until it couldnt be detected.
I am thinking I need to build an op amp. Suggestions please!
