QUESTIONS:
QWhat is the difference between LATCH & FLIPFlop?
Ans: We can easily find the answer after going through the theory given:
 Latches are level sensitive while flipflops are edge sensitive devices
 Hence latches faces problems like glitches in the output while no such problem occurs in flipflops.
 As we can see from different circuits given earlier, we need more gates to implement flipflops than latches.
Q Implement the function of D latch using MUX?
Ans: We know DLATCH can be triggered when CLK is 1 (positive level triggered) or when CLK is 0 (negative level triggered). Hence we can implement both of these as follow:
And we can make a truth table for each of these as:
Those are actually the truth tables for DLATCH. Hence we get the Dlatch using MUX.
Q Implement the function of T latch using MUX & a NAND gate?
Ans: We can achieve the above as follow:
