Explanation:
To understand the output pattern after the second clock pulse, we need to analyze the behavior of a 4-bit serial in/serial out shift register.
Serial In/Serial Out Shift Register:
A serial in/serial out shift register is a type of shift register where data is shifted in and shifted out serially, one bit at a time. In this type of shift register, the data is shifted in from the serial input and shifted out from the serial output.
Initial State:
The shift register is initially clear, which means all the bits in the register are set to 0.
Storing the Nibble 1100:
To store the nibble 1100 in the shift register, we need to input the bits serially, starting from the right-most bit.
1. Clock Pulse 1:
- The right-most bit of the nibble, which is 0, is inputted into the shift register.
- Since the shift register is initially clear, all the bits in the register remain 0.
- The output pattern after the first clock pulse is 0000.
2. Clock Pulse 2:
- The second right-most bit of the nibble, which is 0, is inputted into the shift register.
- The bits in the shift register are shifted to the right by one position.
- The right-most bit is shifted out from the serial output.
- The output pattern after the second clock pulse is 0000.
Output Pattern:
After the second clock pulse, the output pattern is 0000.
Therefore, the correct answer is option C) 0000.

In Serial-In/Serial-Out shift register, data will be shifted one at a time with every clock pulse. Therefore,
Wait | Store
1100 | 0000
110 | 0000 1st clock
11 | 0000 2nd clock.
