This quiz tests your knowledge of important types of SLC circuits (such as data-latch registers, shift registers,synchronous counters and ripplecounters) and their characteristic architectures. (Go back to homepage.) The sequential logic circuit shown represents most closely the basic architecture of a: What are the contents of the shift register shown below (assumed initially cleared) after the input sequence SI = 101111 is applied? (Assume 6 clock pulses are used). Suppose that Q1 = 0 and Q2 = 1 is the initial state of the two JK flip-flop circuit shown. What is the state of the circuit after applying two complete clock pulses? Which of the waveforms shown below can be generated by the output QB of the synchronous counter shown? (QA is least significant) ``` CLOCK _-__-__-__-__-__-__-__-__-__-__-__-__-__-__-__-__-_ QB1 __---------_________---------_________---------____ QB2 __---___---___---___---___---___---___---___---___- QB3 __------------____________------------____________- QB4 __------______------______------______------______- QB5 __------------------------________________________- ``` Suppose that Q1 = 1 and Q2 = 0 is the initial state of the two JK flip-flop circuit shown. What is the state of the circuit after applying two complete clock pulses? Which of the following represent the corrrect transient states which exist between the two ripple counter states shown below? ``` (0011) | V (????) transient state #1 | V (????) transient state #2 | V (0100) ``` If QDQCQBQA = 1011 initially, what are the contents of the shift register below after the input sequence SI = 01 is applied? (Assume 2 clock pulses are used.) How many transient states does a 4-bit ripple counter transit through between count = 7 and count = 8? A binary ripple counter is connected as shown (QA is least significant). Which of the following state sequences does the counter naturally progress through? (ignore transient states)
