    Hello: Thank you for your time you put in the videos. I do not understand one thing in your explanation. You do not mention about the clock input signal in the characteristic and the excitation tables. Why?

    • @EngineeringFunda
      @EngineeringFunda  3 ปีที่แล้ว +1

      Characteristics and Excitation does not includes clock signal. It is already considered that with respect to clock there will be transition in any flip flop

  • @i_Ankit
    @i_Ankit 2 ปีที่แล้ว +6

    Hello everyone :) i believe i how found the explanation to the confusion we are all sitting with.
    How do we get 0 and 1 as Qn in the truth table's two middle cases.?
    First, what we must understand is that Qn represents the value of Q in a Nand-SR flip flop.
    (Q bar) is not represented in this truth table example as it is not relevant in some sence.
    Next, we must for ourselves try to visualize the Q output.
    First, let's put:
    Clock = 1, S=0, R=1.
    through the first nand gate at the top, (in previous lecture) we take 1 and 0 as inputs and get the S* as 1.
    For clock and R as inputs we get 1,1 which is 0 (according to our nand-gate truth table.
    so now we have S* as 1 and R* as 0.
    If we try to remember the SR-latch walkthrough he did a couple of lectures ago,
    we know that whenever S is 1, then Q is automatically 0, and when putting that input into the bottom nand-gate with R* then we get 1. so now we have S = 0, and R = 1.
    However, as mentioned just before, Qn represents the Q, not Q complement.
    So Qn represnets the Q, which is 0. therefore we put the 0 into the truth table as the value of Qn.
    For the third case where S = 1 and R = 0, (clock is ofcourse 1)
    Then the top nand-gate resolves into 1*1 = 0 = S*, and the bottom nand-gate resolves into
    1*0 = 1 = R*. so whenever Reset is 1, then (Q compliment) is 0. and when you use 0 as an input for the top NAND-gate with S* then you get 1..
    Again, it is very important to remember that Qn represents Q in our Sr flip flop truth table in previous lecture, so (Q compliment ) which is 0, is not included.
    So basically if you sit down, draw out the SR flip flop sequential circuit with control input as clock, and take clock as 1, and try both:
    S = 0, R = 1
    S = 1, R = 0
    Then you will get Q as
    Q = 0, (Q Bar) = 1
    Q = 1, (Q Bar) = 0
    But Qn again represnets Q, so the answer for case two would be:
    Case 2: 0
    Case 3: 1.
    I apologize if i said the same words too many times :) but i don't want to loose anyone :)
    on beforehand :) thank you :)
