It's urgent please solve asap.... And please don't copy answers on other platforms are wrong. b. Design a circuit that stores the last two bits of the current sum, adds a 2-bit input number"A" to the sum, and has one output wire "O" that is a "1" whenever the sum + A is amultiple of 4. You may use 2 D flip flops to store the last 2 bits of the sum, and also2-input AND gates, 2-input XOR gates, and 1-input NOT gates. Do not worry about yourflip flops including a clock line, enable line, or a reset line (to clear the sum). Assume anew array value is available on every negative clock edge

Design a sequential detector that detects the code 1011 using T flip flops and any other gates. Show all steps of sequential logic desig. Then apply to circuit maker to prove the results.
Design 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).

(b) Consider the following three different approaches of implementing the sequential logic circuit Sketch the logic diagram of the circuit for each case (i) Use a negative-edge triggered D flip-flop and some primitive gates (i) Use a positive-edge triggered JK flip-flop and some primitive gates (ii) Use a positive-edge triggered T flip-flop and a 4x1 multiplexer
5. 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.

(b) Describe the function of the counter (e.g. binary down counter counting from 7 to 0).

answere fast please question from DIGITAL LOGIC DESIGN TOPIC : Designing Combinational Logic You are designing a water level circuit using 74ALS151 (8 to 1 Multiplexer IC)* When input is 0000 that means tank is empty.* When input is 1111 that means tank is full.* When input is below 5, that means water level is low.* So, make a circuit using 74ALS151 Multiplexer IC that shows a "low water" indicator light(by setting an output L to 1) when the water level drops below level 5.

Flip-flops are basic memory element used in sequential circuits. Flip-flop has two stable states – logic 0 or logic 1. A flip-flop will either be in one of the two stable states after application of the input signals; it will remain to be in that state even if the inputs are removed. Flip-flops are also known as the latch or toggle.(a) (i) What is the difference between D flip-flop and JK flip-flop. (ii) How will you convert a D flip-flop to J K flip-flop? (b) Realize the following function of three variables with 8:1 MUX.
