Q.
In the following circuit what are $P$ and $Q$:
KCETKCET 2020Semiconductor Electronics: Materials Devices and Simple Circuits
Solution:
A $NAND$ gate gives an output $1$ if at least one of the inputs is zero.
Hence $Q$ is $1$ .
Therefore, the inputs for the upper $NAND$ gate are $1,1 $.
Hence $P =0$.
