Please be as detailed as possible, I'm really struggling with
understanding this.
Consider a new type of a positive edge-triggered flip-flop that we call the AB flip-flop. The characteristic equation of the AB flip-flop is Q = AQ+B. Moreover, the mode AB = 11 is not allowed. 2.1 Complete the table below. A B Mode Q 0 0 0 1 B Q A 1 0 CLK 1 1 Not allowed (Forbidden) 2.2 Complete the excitation table of the AB flip-flop. * А B Q 0 0 0 1 0 1 2.3 Implement the AB flip-flop using an RS flip-flop and logic gates. 2.4 Using AB flip-flops, design a counter that counts 2, 1, 0, and repeat.
