Realize a Moore machine with one external input S and a 3-bit output 020100 representing a 3-bit binary number. The circuit outputs indefinitely either the sequence of values 1, 3, 5, 1, 3, 5, 1, 3, ... when S=1, or the sequence of values 1, 5, 3, 1, 5, 3, 1, 5, ... when S=0. Use a binary state encoding with exactly 2 D flip-flops. You can decide when transitions between the sequences occur, the new sequence can start at any digit. On reset the system starts by showing the number 3. i) write the state diagram; include the transition conditions and the output value; ii) write the truth table for the next state; iii) write the truth table for the output;

The following expressions of X and Y are accurate representations of the implementation under using an active-high decoder and two OR gates. Select one: O a. True O b. False X(a,b,c) = abc' + abc + ab'c + a'bc Y(a, b, c) = a'bc + a'b'c + ab'c + abc b 5 6 7 X

You are asked to design a circuit to detect if an overflow occurs when subtracting two integers represented in two's complement: Z= X - Y. Let Sz, Sx, and Sy be the sign bit for Z, X, and Y respectively, and they are fed as input to the circuit. Let O be the output bit of the circuit, whose value is 1 if an overflow happens, and 0 if otherwise. a) Build the truth table for O as a Boolean function of Sx, Sy, and Sz. b) Write the canonical expression (sum-of-product) for the Boolean function defined in the part a. c) Implement the Boolean expression defined in part b with a circuit by using AND, OR, and NOT gates. Draw the wiring diagram.

For the truth table above where wx input is down and the y input is across, which one of these is a simplified expression? F(w,x,y)=w+x F(w,x,y)=w'(w+x+y') F(w,x,y)=y+w+x F(w,x,y)=w'+w+x F(w,x,y)=w'+xy'

In the following circuit, the 3 bit up-counter counts from Q2Q1Q0-000 to Q2Q1Q0= 111. Q2 is the most significant bit and Qo is the least significant bit. Assuming the 3-bit up-counter is initialized to be Q2Q1Q0-000. The 3-to-8 decoder has output C, which has 8 bits, and is specified as C7 C6 C5 C4 C3 C2 C1 Co (Co is the least significant bit). Which statements below correctly describe the circuit? Choose all that apply. clock С7 С6 С5 С4 С3 С2 С1 С0 3 to 8 decoder Q2 Q1Q0 3 bit up-counter

Write VHDL code for this FSM. Add an asynchronous RESET, active High to the state diagram.

you need to design and draw a 3-bit synchronous binary up/down counter for experiment 5. You need to add a bit named "M" for the excitation table that helps it switch between up and down mode and draw the state transition diagram, excitation table, k-map and circuit diagram with T-flip flops. When M = 0, it will perform up counter. When M = 1, it will perform down counter.

Find the maxterm expansion of the truth table and create a digital circuit that works with it.

Using MATLAB compute the convolution of the following signals: a) x (n) = {1,2,4}, h (n) ={1,1,1,1,1} Also, plot the convolution.
