Shift Registers - General Questions (7)

A bidirectional 4-bit shift register is storing the nibble 1101. Its  input is HIGH. The nibble 1011 is waiting to be entered on the serial data-input line. After three clock pulses, the shift register is storing ________.

On the third clock pulse, a 4-bit Johnson sequence is Q₀ = 1, Q₁ = 1, Q₂ = 1, and Q₃ = 0. On the fourth clock pulse, the sequence is ________.

What is a shift register that will accept a parallel input, or a bidirectional serial load and internal shift features, called?

The bit sequence 0010 is serially entered (right-most bit first) into a 4-bit parallel out shift register that is initially clear. What are the Q outputs after two clock pulses?

On the fifth clock pulse, a 4-bit Johnson sequence is Q₀ = 0, Q₁ = 1, Q₂ = 1, and Q₃ = 1. On the sixth clock pulse, the sequence is ________.
