Hi,
I am building a small computer with a 4-bit 16 colour video output that will go into a monitor that has 1500 ohm impedance.
Please could someone tell me what resistor values I need to use to convert the 4-bit digital o/p to the required analogue signal in the R2R ladder?
Also, if you could explain how you work it out, that would be great!!
Many thanks,
Matthew
