Question
The flip – flop that cannot be used to construct a serial shift register is_____Select one:1.D – flip flop2.SR flip – flop3.T flip – flop4.JK flip – flop
Solution
The flip-flop that cannot be used to construct a serial shift register is the SR flip-flop.
Here's why:
-
D flip-flop: This can be used in a shift register. The D (Data) flip-flop has a single data input. The value at the data input is transferred to the output at the rising edge of the clock pulse.
-
SR flip-flop: This cannot be used in a shift register. The SR (Set-Reset) flip-flop has two inputs, one for setting the state and one for resetting the state. This flip-flop doesn't have the data input, which is necessary for a shift register.
-
T flip-flop: This can be used in a shift register. The T (Toggle) flip
