Fast AND gate.

    I have searched around and found mostly the typical NTCT AND gate in tpt.  I have also seen one made with switch.  Both have serious limitations.  I have been experimenting and have made a very responsive and gate that only lets 1 spark out per parallel pulse event.  It is demonstrated here in an array to form a multiplexer connected to my 16 bit ROM.  The AND gate is very fast to turn on and off.

     Mind explaining what exactly is an AND gate?

     Most gates require one input. Basically, this is a gate which requires two inputs to fire off a spark. However, unlike swch they can be any order.

    A "gate" is somewhat analogous to a "function". It takes some inputs, and based on their values, outputs some value. In context of TPT, inputs and outputs are most likely SPRK signals. So a gate in TPT is merely an electronic device, that takes a combination of sparks (or lack thereof), and outputs (or doesn't output) a spark.

    For instance, the NOT gate has 1 input and 1 output. If the input is active, the output is not active, and vice versa. In sense of TPT, it's a device, which generates sparks whenever it *isn't* sparked. An OR gate is a device that activates its output if *either* of the inputs are active, and deactivates if both are off. An AND gate, on the other hand, works kind of the other way around. It produces a spark, if *both* of inputs are sparked.

    nice description mniip.
