What is strong 1 and strong 0 concepts in an inverter

Question

Accepted Answer

Strong 1 and strong 0 are the maximum voltage levels that an inverter can output for logic 1 and logic 0 respectively.

Strong 1 is the maximum voltage level that an inverter can output for logic 1.
Strong 0 is the maximum voltage level that an inverter can output for logic 0.
These concepts are important in determining the noise margin of a digital circuit.
The noise margin is the difference between the minimum voltage level that represents a logic 1 and the maximum voltage level that represents a logic 0.
For example, if the strong 1 level is 3.3V and the strong 0 level is 0V, then the noise margin is 3.3V.
The strong 1 and strong 0 levels are determined by the technology used to fabricate the inverter.
In CMOS technology, the strong 1 level is typically equal to the supply voltage, while the strong 0 level is close to 0V.
