The logic circuit as shown below has the input wave forms $$A$$ and $$B$$ as shown. Pick out the correct output waveform.

By adding certain impurities to                   in the appropriate concentrations the conductivity can be well-controlled.

When you have a P-N junction and you connect it to a DC voltage, this will lead 

The truth table of the combination of the logic gates shown in the figure is

In this $$I-V$$ characteristic curve of a zener diode, regions 1 and 2 respectively indicate

Electrons always moves from

The following symbol represents

The logic behind NOR gate is that which gives

The diagram of a logic circuit is given below, the output of the circuit is represented by

In the circuit below, $$A$$ and $$B$$ represent two inputs and $$C$$ represents the output.
The circuit represents
