Hi everyone,
I am building a hardware DCC encoder and am stuck at what should be a fairly trivial point.
I have a square wave pulse that goes from +5V to 0V. Basically I need this pulse to be symmetrical around 0V so I need it to go from +2.5V to -2.5V. ( I will then amplify this using an op amp).
Could anyone please suggest how I could do this please?
many thanks,
B
