a not gate or an inverter
Alternates between 0 and 1
A logic gate is an elementary building block of a digital circuit. Most logic gateshave two inputs and one output. ... The following illustration and table show the circuit symbol and logic combinations for an AND gate. (In the symbol, the input terminals are at left and the output terminal is at right.)
A XNOR gate for comparing 2 inputs
An AND circuit is a circuit that takes two or more inputs, and generates an output that is the boolean AND function of those inputs. Two light switches in series, for instance, is an AND circuit because both switches have to be on for the light to be on. If the switches were wired in parallel to each other, and then in series with the light, that would be an OR circuit.
The SCR turns on based on gate voltage. The firing angle will depend on the point in the AC cycle where the gate voltage is where you want it, so the firing angle is a function of circuit design, not of the SCR.
The thyristor is basically used a switch in an AC circuit to control the amount of power fed to the load. To turn on this switch an "electric" pulse should be applied to the Gate terminal of the Thyristor. A circuit which supplies the "electric" pulse is called the firing circuit.
By controlling the amount of gate current !!
Gate circuits should be isolated from the main power circuit to avoid any damage to the power circuit if gate is damaged.
India gate, and some other gate i don't remember
74s32
It has 3 inputs. They are source, n gate, p gate and only one output that is drain
K = 1 [π − α + 1 sin(2α )] is the formula of calculating the SCR firing circuit diagram with diode.
Only if you decide to work with negative logic throughout the circuit.

To make a full subtractor, you need an XOR and a NAND gate.
