- : Design a 2-bit synchronous counter that behaves according to the two control inputs A and B as follows. AB 00: Stop counting; AB = 01: count up: AB 10 or AB =11 the counter count down. Using T flip flops and any needed logic gates? %3D %3D1.) A storage register made up of six D flip-flops is storing a binary word. The flip-flop status are: A = set, B = set, C = reset, D = set, E = reset, and F = set. The A flip-flop is the LSB. The decimal equivalent of the register content is 2.) D flip-flops are most frequently used in5. JK flip-flops are often used to build counters. The JK flip-flop will toggle the original output value when triggered by the clock signal if both the J,K inputs are connected with a constant "high"(logic 1). All the JK flip-flops in Figure 2 are negative edge triggered. All the initial values of Q2Q1Q0 are 0. Qo (LSB) (MSB) Input K K Logic 1 Input Q2 000 Figure 2. Counter (a) Sketch the output waveforms forQ2 Q1 Q0. Write down the output binary value (Q2Q1Q0: such as "000", "001") for each clock period on the figure. (b) Describe the function of the counter (e.g. binary down counter counting from 7 to 0).
