HIGH CLK- CLR nnnnnnn CLK PR CLRQ#01: The schematic shown in figure below is for Divide_by_11, a frequency divider, that divides clk by 11 and asserts its output for one cycle. The unit consists of a chain toggle-type flip-flops with additional logic to form an output pulse every 11th pulse of clk. The asynchronous signal rst is active-low and drives Q to 1. Develop and verify a model of Divide_by_11. Vcc 20LSB Q2 03MSB clk clk clk clk clk rst rst rst rst wl w2 clk QB cik_by_11 rst rstDesign the following combinational logic circuit with a four-bit input and a three-bit output. The input represents two unsigned 2-bit numbers: A1 A0 and B1 B0. The output C2 C1.C0 is the result of the integer binary division A1 A0/B1 B0 rounded down to three bits. The 3-bit output has a 2-bit unsigned whole part C2 C1 and a fraction part CO. The weight of the fraction bit CO is 21. Note the quotient should be rounded down, i.e. the division 01/11 should give the outputs 00.0 (1/3 rounded down to 0) not 00.1 (1/3 rounded up to 0.5). A result of infinity should be represented as 11.1. A minimal logic implementation is not required. (Hint: start by producing a truth table of your design).
