Redstone circuits/Logic/subtraction xor gate

Basic Subtraction XOR Gate

3×4×2 (24 block volume)
flat, silent
circuit delay: 1 tick

The block can be replaced by redstone dust.

Repeated Subtraction XOR Gate

4×4×2 (32 block volume)
flat, silent
circuit delay: 2 ticks

Any of the blocks can be replaced by redstone dust.

Inverted Subtraction XOR Gate

4×4×2 (32 block volume)
flat, silent
circuit delay: 2 ticks

The output block can be replaced by redstone dust.
