Comparators Part 1

thanks for this bro. I'm a visual learner so it's nice to have lectures outside of the class

3:35 Sir I think you have the inputs wrong. The reason for this is because say You had 2 bit, 2 binary strings "00" and "11" in the first string Ao=0 and Bo=0 the XNOR will output a 1 and for the second string you have A1=1 and B1=1 which gives the output of 2nd XNOR a 1 which in turn makes the AND gate produce 1 but this is WRONG. 00 does not equal 11, what the inputs SHOULD be in order for this to work is A0 and A1 XNOR gate1, Bo and B1 at the 2nd XNOR gate. I love your videos very helpful/clr

Thank you so much for such a clear explanation.

Thank you Mr Pytel

@Kbomba3
Actually his inputs are fine
if you have 00 and 11, A0=0, B0=1, A1=0, B1=1
so your inputs into 1st XNOR gate will be a 0 (A0) and a 1 (B0), which produces a 0(E0).
the inputs into 2nd XNOR gate also will be 0(A1) and 1(B1), which will produce a 0(E1). Both of these 0's get AND'd to produce a 0. Proving that they are inequal,

I'm working on an analog project and if I were to use a comparator, how would the input and output work with varying voltages?
For instance, Input A starts at 4v and decreases to 0v. Input B starts at 0v and rises to 4v. Will the Output be 0v until they both reach 2v, and if so would the output be 4v when they match?
