Questions tagged [circuit-diagram]

A circuit diagram (also known as an electrical diagram, elementary diagram, or electronic schematic) is a simplified conventional graphical representation of an electrical circuit.

Circuit diagrams are pictures with symbols that have differed from country to country and have changed over time, but are now to a large extent internationally standardized. Simple components often had symbols intended to represent some feature of the physical construction of the device.

Common schematic diagram symbols (US symbols)

Writing an expression using only NAND, OR, XNOR

I have a 2-1 mux and I'm trying to write z = s'd0 + sd1 using only NAND, XNOR, and OR gates (not necessarily all of them). I tried simplifying it and what I ended up with is z = NAND(NAND(s', d0), NAND(s, d1)), but I can't use NOT ('), so is there a…
