Build the circuit shown here using a NAND gate. Test the function of the circuit by carrying it through the truth table shown below. What logic function does a NAND gate mimic when connected this way? Input A Output gate. 1 Build the circuit shown here using NAND gates. Test the function of the circuit by carrying it through the truth table shown below. What logic function do NAND gates mimic when connected this way? 4. A gate. Input A Input B Output 1 1 1 1 Build the circuit shown here using NAND gates. Test the function of the circuit by carrying it through the truth table shown below. What logic function do NAND gates mimic when connected this way? 5.

Need help with this. Please.

6. Predict the output from each gate for the input variables shown: C A D B E Find out the values of C, D, E, F and G (show your calculation how you are getting the numbers) Input: A = 0 and B = 0 Find C, D. E, F, and G Each answer will be either 0 or 1

2. Design a logic circuit with two inputs and 4 outputs, with each of the outputs hooked up to an LED. Only the first LED should light up when the input values are 00. Only the next LED should light up with the input values are 01. Only the following LED should light up for 10, and only the last LED should light up for input 11. Thus for each input combination, you should have one LED only being lit. This is called a DECODER circuit, you are decoding 2 bit binary input to one of 4 discrete outputs. a. Create the truth table (use the standard truth table format). b. Write a Boolean expression that corresponds to the truth table.
