4. Design a four input EXOR gate using 3 X 8 decoders and extra gates.
Design 3- to – 8 decoder using logic gates with enabler, AND, NOT, etc..? Design 3- to – 8 decoder using only two 2-to-4 decoders graphical blocks, use enabler input? a) Design a 3-bit ripple-carry adder using AND, OR, NOT, EXOR, etc.; include carry-in (Cin), carry-out (Cout) and overflow input/output signals? Note: Design for 1-bit first, then extrapolate to 4-bit using 1-bit full-adder graphical block. Design a 3-bit ripple-carry subtractor using AND, OR, NOT, EXOR, etc..; include carry-in (Cin), carry-out...
Q.2) Using De Morgan's law: a) Design a 3-input NOR gate using 2-input NOR gate only. Draw you diagram b) Design 4 input AND gate using 2 input NOR gates. Draw you diagram
Design a 32-input Mux using 8 and 4 input multiplexers. Design 4 to 16 decoder using 3 to 8 decoders. 6.
Design a 3 input NOR gate using n-channel and p-channel enhancement M - Use NAND gates to make a circuit that functions as: a) an inverter b) an AND function c) an exclusive OR (XOR) Function
Design the circuit for f(A,B,C,D)=ΠM(0,1,4,7,8,12-15),d(2,3,10) using a minimal number of 3-to-8 line decoders and NAND gates (any size). Decoder outputs must be active-low. Also, assume that the decoder has one active-high enable line G0. If you need NOT gates, you must show them in the diagram using NAND gates.
PRELIMINARY WORK 2: FUNCTIONS OF LOGIC GATES F (xyz) Figure 2.1-3-input-NAND Gate design by using just 2-input-NAND Gates Figure 2.2- Design of function F-xy+x'z, by using just 2-input-NAND Gates Simulate the logic circuits that are given in figure 2.1 and figure 2.2. Simulations can be done in Proteus, P-Spice or any simulation program that you want to use. You can take screenshot of your design for print out. Please fill the table 2.1 according to your simulation results. Experiment results...
Using building blocks such as binary adders, comparators, multiplexers, decoders, encoders, and arbiters as well as logic gates, design an 8x2 popularity circuit – a circuit that accepts eight two-bit numbers and outputs the number of times each of the four numbers appears on the input.
Use 3-to-8 lines decoders to achieve the following: (Decoders should have one active-low ENABLE input, active-high binary code inputs, and active-low outputs. You can use additional gates) F = Σ A,B,C,D (2,4,6,14)
