About Ternary Inverter Gates
In Symmetric Ternary logic, 5 inverters can be made. We will consider only three of them because these gates are used in ternary computing.
Ternary clock with debug
Finally, I finished the ternary clock. It includes additional components to make it more easy to debug.
It starts working...
We have an update. The clock and ternary AND logic gates are built and tested. And, they works... See the image and videos below:
Eight TAND gates.
Base Logic Gates: First steps
We started to build ternary base logic gates. And it's working. Today will be no much text, the principles where described in anterior posts. This post will be an images post to show how it works in practice. So, let's begin...
ROLUAN: Ternary "OR" and "XOR" Gates
The ternary "OR" is very similar to Ternary "AND" gate. In the circuit schema we changed just two things: changed the place of transistors and changed the voltage sources: positive with negative. And voila: we have a ternary "OR" gate.
Because the ternary logic is a little bit more complicated (in fact, it is much simpler, but we will discuss that thing later :) ), let's do the same steps as we done in the previous post. Ok, let's start:
ROLUAN: Ternary "AND" Gate
What is "AND" gate? If in short, it represents the minimum value between two ternary inputs (trits, that can have one of the following states: "-1", "0" or "1"). So, if we will have two inputs, "A" and "B", then the ternary "AND" circuit should choose the minimal value of them and pass the result further. For more details, see the article on wikipedia. This result can be an input for another ternary gate, or a final result, stored in a memory circuit.
We already know the "AND" ternary formula, or, more correctly, ternary "AND" truth table:
ROLUAN: Ternary "NOT" Gate
As we know, all computer calculations are done through hardware circuits. Depending of those circuits schemas, we can do adding, subtraction, multiplying and so on. But, at the base of all calculations there are just a few base gates, and their combination permits to the processor to make really complicated things.
Today we will describe one of these base gates: NOT gate.
We will not go into description of what is a transistor, or voltage supplier, ground, etc. We will just describe the schema and how it works.
For the ternary inverter, we should know first the truth table for it. It is represented in image below:
