QUIZ 4
Version 1

Question 1:
A Parallel-in/Serial-out shift register is loaded initially with 1010. What will the register contain after two clock pulses if the serial input is LOW?
Question 2:
What is the Modulus of a 5-bit Johnson Counter?
Question 3:
An 8-bit Serial-in/Parallel-out (SIPO) shift register is initially loaded with 00110101. After two clock pulses, what data will the shift register contain if the
serial input is HIGH?
Question 4:
A 74194 Universal shift register has a LOW on the shift left data input, a HIGH on the shift right data input, and it is loaded with 0110. What data will the shift
register contain after two clock pulses in the shift right mode?
Question 5:
What function is performed by a 74194 Universal shift register if the select inputs are S1 = 0 and S0 = 1?
