Design a counterwhich hasone input, x, and four outputs, c, b, a, and z. output signals c, b, and a are three flip-flop outputs which form a three-bit binary number with a as the least significant bit (lsb)and c as the most significant bit (msb). this binary number will be displayed as a digit on one of the 7-segment led displays on the pb-505digital lab. note that the flip-flop outputs are labeled c, b, a, to match the inputs of the display on the pb-505. when x
