using five(5),2 to 4 line decoders with active low enable inputs and active low outputs, and a 4 input NAND gate, draw the circuit diagram that implements the following function. F(W,X,Y,Z) = (Z( W'( X'Y +XY')+W(XY+XY')
Draw a 4:16 Decoder that has no enable input (so 4 inputs and 16 outputs) using only 3:8 Decoders that have the enable input hardcoded to a 1. No other gates allowed.
3. Consider a tri-state inverter with an active-high enable. (So the output of the buffer is enabled when the enable signal is high, and is in tri-state when the enable signal is low.) Complete the truth table. En A Out 0 0 0 1 10 AoOut En (active high) 4. Consider an open-collector buffer. Complete the truth table. A OU 1 AO-Out
1. Provide the function table of a 3-to-8 active-low output decoder with active-low enable input. 2. A function f (D,C,B,A) is synthesized by a 4-to-16 decoder as in Figure 1.

Construct a 4-to-16-line decoder with an enable input using five 2-to-4-line decoders with enable inputs.
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)
Design a 4-to-2 priority encoder with active-low outputs. (a) Construct the truth table. (b) Derive a Boolean expression for each output. (c) Draw a circuit diagram.
1. i. Design and test a 3-to-8 decoder with active-low outputs using VHDL/HDL. Demonstrate your outputs in the BASYS board. (Note: Capture the pictures of your output and add in in your answer script) ii. Include (screenshot) VHDL codes and .xdc file modification in your answer script. ili. Develop a truth table following your outputs. (Note: You do not need to show step by step procedures, except what were asked in the questions]
Task (10 points): (1) Approach 1: Implement a 4-to-16-line decoder using the schematic capture feature of Xilinx ISE. On the schematic, add a text that clearly shows your name and eRaider ID. (2) Approach 2: Write and compile a 4-to-16-line decoder Verilog gate-level description. (3) Approach 3: Write and compile a 4-to-16-line decoder Verilog behavioral description. (4) Create an appropriate test file to do an exhaustive test. Exhaust all the possible input codes in 3 the following order: 0000 →...
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.
