Which of the following gates serves as the building blocks is digital circuits?
NAND and NOR gates
The OR or the AND or the NOT gates alone cannot give a different gate by repeated use, i.e., two or-more OR or AND or NOT gates do not yield a new gate. But the repeated use of NAND (or NOR) gates can give all other gates like OR, AND and NOT. Hence the NAND (or the NOR) gate serves as a building block in digital circuits.
In a silicon transistor, a change of 7.98 mA in the emitter-current produces a change of 7.8 mA in the collector-current. Find the required change in the base current to produce an equivalent change in the collector current.
A common-emitter transistor amplifier has a current gain of 50. The collector resistance is and the input resistance is , calculate the output voltage if input voltage is 0.01 V.
