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)?...

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.

Answers are at the end of the chapter 1. If an S-R latch has a 1 on the S input and a 0 on the R input and then the S input goes to 0, the latch will be (a) set (b) reset (c) invalid (d) clear 2. The invalid state of an S-R latch occurs when (c) S 1,R-1 (d) S-0, R-O 3. For a gated D latch, the output always equals the D input (a) before the enable...

Design a system whose output goes high only after 8 consecutive
1's appear on the input; once the output goes high, it takes four
consecutive 0's on the input to make the output go low again. You
will use one switch as the input, and one button as the clock.
Assign a binary state code to each state of your FSM.
On a piece of paper, develop a truth table for the next state
and output logic.

5483A 4-Bit Binary Full Adder with Fast Carry General Description The '83A high speed 4-bit binary full adders with internal carry lookahead accept two 4-bit binary words (Ao-A3, Bo- B3) and a Carry input (Co). They generate the binary Sum outputs (So-S3) and the Carry output (C4) from the most significant bit. They operate with either HIGH or active LOW operands (positive or negative logic)....
