Hello everyone,!
I was given a hard question from my "control system" professor ,the question is: there are two input through a op-amp(+12Volt and -12Volt),so, how to achieve that "when the +12V through the circuit, the current has a deriction, and when the -12V is applied, the current has another direction?" Can I use the "Howland Current Pump"? If not, what can I choose?
Thank you!
