Solution:

A shift register is a digital circuit that shifts the bits in a digital signal to the left or right by a specified number of positions on each clock pulse. A 3-bit ring counter is a type of shift register that shifts the bits in a circular fashion. Suppose the applied input sequence to the 3-bit ring counter is 110, after how many clock cycles will the same sequence appear?

one

four

six

three

Solution:

Which of the following statements are true?

Asynchronous events does not occur at the same time

Asynchronous events are controlled by a clock

Synchronous events does not need a clock to control them

Only asynchronous events need a control clock
