A prime mark means the complement, so A′ reads as not A.

NAND and NOR are each functionally complete: any logic function at all can be built from copies of one gate type.

Questions about the Logic Gates poster

What’s on the Logic Gates poster?
A 7-row table: Gate · Expression · Output is 1 when. A prime mark means the complement, so A′ reads as not A. AND — A · B — Both inputs are 1; OR — A + B — At least one input is 1; NOT — A′ — The input is 0; NAND — (A · B)′ — Not both inputs are 1; NOR — (A + B)′ — Both inputs are 0; XOR — A′B + AB′ — The two inputs differ; XNOR — AB + A′B′ — The two inputs match. NAND and NOR are each functionally complete: any logic function at all can be built from copies of one gate type.
Who is the Logic Gates poster for?
Logic Gates belongs to the Electrical Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning digital logic can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Logic Gates poster?
Use it to move between a gate name, its algebra and the condition that makes it fire. A wall chart earns its place by being glanceable from where the work is happening, so Logic Gates belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
What other posters go with Logic Gates?
Adders, Boolean Algebra and Counters & Registers sit alongside Logic Gates in the Electrical Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.AddersBoolean AlgebraCounters & Registers
Is the Logic Gates poster free to download and print?
Yes. Logic Gates downloads as a free PDF with no account, no email and no watermark, like everything else in the Electrical Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Logic Gates poster print at?
Logic Gates is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Logic Gates loses nothing.Printing guide
