When applying DeMorgan's Theorem visually, the bubble at the output of a two-input NAND gate can be pushed into the gate and it becomes:

An OR gate with two bubbles at its input.

A digital circuit can be constructed using the following devices (multiple answers possible:

FPGAs Relays Transistors

It takes fewer transistors to make an AND gate than a NAND gate.

False

Following is true for a Normally Closed relay:

Its contact OPENS when it is energized.

The gates that meet the criteria for Universal Gates are (multiple answers possible):

NOR Gate NAND Gate

The disadvantages of using relays over transistors include (multiple answers possible):

Relays are slower than transistors Relays consume more power than transistors.

A Field Programmable Gate Arrays (FPGAs) uses memory to store the truth tables and its operation can be summarized in the following steps:

Step 1: Read the inputs. Step 2: Look up the truth table in the memory. Step 3: Output the correct value(s) based on the inputs and the truth table.
