Question
Can you please answer these questions as whole and in detail? It is very important for me.
Please make sure that they are correct else it is going to be very bad for me. I did some of them but I need to check with you to see how would you go through doing these
thanks
Difference between a flip-flop and a lutch. How many flip-flops does a module 16 have? (4 flip-flop is the answer but why?) Find Q0, Q1, Q2 Why do they divide? Difference between syncrohes and a syunchronus? Draw Q0, Q1, Q2 waveform for circuit below Write program for mod-10 counter Write velocity code and include in your code for the flip flop belowExplanation / Answer
1)
a)Differnce Between Latch and Flipflop:
The main difference between latches and flip-flops is that for latches, their outputs are constantly affected by their inputs as long as the enable signal is asserted. In other words, when they are enabled, their content changes immediately when their inputs change. Flip-flops, on the other hand, have their content change only either
at the rising or falling edge of the enable signal. This enable signal is usually the controlling clock signal. After the
rising or falling edge of the clock, the flip-flop content remains constant even if the input changes.
b)To find no of Flip flop, counter lenth N=16, N=2n ; where n is no of flipflop, N=16, n=log216; n=4
c)T Flip flop output will toggle half the rate of clock frequency. in circuit the output of each flipflop as applied to clk to next flip flop. thats why its divide by 2
d)
Difference between synchronous and asynchronous sequential circuits:
Synchronous Sequential Circuit: Output changes at discrete interval of time. It is a circuit based on an equal state time or a state time defined by external means such as clock. Examples of synchronous sequential circuit are Flip Flops, Synchronous Counter.
Asynchronous Sequential Circuit: Output can be changed at any instant of time by changing the input. It is a circuit whose state time depends solely upon the internal logic circuit delays. Example of asynchronous sequential circuit is Asynchronous Counter.
