Consider the circuit below. The switches are controlled by logic variables such that, if A is high, switch A is closed, and if A is low, switch A is open. Conversely, if B is high, the switch labeled is open, and if B is low, the switch labeled is closed. The output variable is high if the output voltage is 5V, and the output variable is low if the output voltage is zero. a. Write a logic expression for the output variable. b. Construct the truth table for the circuit. Logic 1 5 V + A IB В Logic ( C www R

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).

Reduce the Boolean function specified in the truth table below to its minimum SOP form using K-map, where A, B, C are the inputs while X are the outputs.

Digital logic design Solve it with drawing and simulation lab I need them both to have the full solution. And thanks Design counter that counts from 00 to 59, using the IC 74LS90 ripple counter and use two 7 segment display to display the result count. You can also use 7447 binary to 7-segment Display Decoder.

1. Design a combinational logic circuit with three inputs A, B and C and one output X. When only one input is 1, output is 1. When none of input is 1, output is also 1. Otherwise, output is 0.

a) Design a logic circuit with three inputs A, B, C and an output that goes LOW only when A is HIGH while B and C are different. Draw and upload the circuit if you can, or at least describe it in words. b) Which logic gates produce a 1 output in the disabled state? c) Which logic gates pass the inverse of the input signal when these gates are enabled? d) What is the normal resting state of the SET’ and RESET’ inputs of a latch circuit (the prime is same as bar)? What is the active state of each input? e) What is the normal resting state of the NOR latch inputs? What is the active state?

8. The output of a two input AND gate is one only when (a) its either input is one (b) its both inputs are one (c) its either input is zero (d) its both inputs are zero 9. The output logic level of an OR gate is one. (a) if both inputs are zero (b) only if both inputs are one (c) if either or both inputs are one (d) if the inputs are neither zero nor one 10. If two inputs of a NAND gate are shorted, then it is equivalent to (a) an OR gate (b) a NOT gate (c) AND gate (d) NOR gate
