Implement a Combinational Circuit

April 4 by Bina

Implement a combinational circuit defined by the functions given define below.

First function is true when all three inputs (A,B,C) are the same (000, 111). That is, 
F1(A,B,C) = ∑ ( m0, m7)
The second function F2 is true when the input (A,B, C) is a palindrome (010, 101). That is,
F2(A,B,C) = ∑ ( m2, m5)

Implement these functions using a (i)3X8 decoder chip 74138 and (ii) a 4 dual input NAND gate chip 7400, shown below.

Instructions

1. Draw the connections on the sheet with the ICs.
2. Identify the ICs and the breadboard in your lab kit
3. Place the IC firmly on the breadboard. Make the connections using jumper wires.
4. We will provide the test pattern to test your circuit. Output will be tested using LEDs, one each for the two functions.

Implement and test a Sequential Circuit

April 4 by Bina

Implement a sequential circuit defined by the functions given define below.

Implement a 2-bit counter that counts through the counters (0,1,2,3). 
The clock signal that triggers the count will be provided as a test signal.
You will do this exercise only on paper.  The chip is not in your kit.

Instructions

1. Study and understand the chip 74107 that is a dual JK flip-flop.
2. Draw the state table for the 2-bit counter and derive the functions for JA, KA, JB, KB.
3. Draw the connections on the sheet with the 74107 IC.
4. Draw the required inputs on paper.
