Below is the diagram for an S-R Latch using NAND gates. Assume the NAND gates each have 15 nS propagation delay. The system starts with the conditions -S is HIGH, R is HIGH, Q is LOW, and Q is HIGH state, and has been stable in that state for a significantly long time. Now, at some time to, we bring the “S input to the zero state. How long before NOT Q is valid (in a final stable state)? S...
5. Below is the diagram for an S-R Latch using NAND gates. Assume the NAND gates each have 15 nS propagation delay. The system starts with the conditions ~S is HIGH, R is HIGH, Q is LOW, and Q is HIGH state, and has been stable in that state for a significantly long time. Now, at some time to, we bring the ~S input to the zero state. How long before NOT Q is valid (in a final stable state)?...
NAND and NOR gates are universal, which means that you can implement every possible Boolean function with them. Remember that the NOT gate can be implemented using either a NAND or a NOR. Implement the following functions using only NAND and NOT gates. Do not simplify the functions for this problem. a. (a + b) (c' +d) b. (a'b + b'c)' Implement the following functions using only NOR and NOT gates. c. (a + ab'c)' d. (((a + b)' +...
a) Draw an SR-latch using only NAND gates. Label each input and output, and label all wires with a name if the wire does not connect to any input or output b) Describe the behavior of the latch when S and R are both 0. What is the output of each gate? c) Assuming that the latch starts with S = R = 0, write down the sequence of what happens when R = 1. Discuss changes at each point...
9. (15 points) The D latch shown in lecture 15 slide 15 is constructed with four NAND gates and an inverter. Consider the following three other ways for obtaining a D latch, and in each case draw the logic diagram and verify the circuit operation Use NOR gates for the SR latch part and AND gates for the other two. An inverter may be needed. Use NOR gates for all four gates. Inverters may be needed. i. ii. Use four...
For an S-R latch (with NAND gates), what is the next state of Q' if S=0 and R=1? A. Q(t+1)=1 B. No change C. Q(t+1)=0 D. Forbidden
10.5 This refers to the S' input for the NAND version, i.e., you don't have to include an inverter for S. 10.8 Start with Q = 0, Q = 1. Hint: be sure to remember what you observed in the previous problem! 10.5 → Would you expect the propagation delay from the set input to the Q output to be faster in a set-reset latch built from a pair of NAND gates or one built from a pair of NOR...
please solve all parts of the question
Problem #1 The D latch is constructed with four NAND gates and an inverter. Consider the following three other ways for obtaining a D latch. In each case, draw the logic diagram and verify the circuit operation. (a) Use NOR gates for the SR latch part and AND gates for the other two. An inverter may be needed. (b) Use NOR gates for all four gates. Inverters may be needed. (c) Use four...
What is the term for a set of flip-flops and the gates that implement their state transitions? 1. (a) Full Adder 2. (b) Moore machine 3. (c) Register 4. (d) Decoder 5. (e) None of (a) through (d) is the correct answer. A D flip-flop has a D latch and a SR latch. The D latch is connected directly to the clock (no inverter). This type of flip-flop will be able to change state when the clock is 1. (a)...
