Yadav 4 1,2,3 Student, Dept. To check systems performance on a practical system there is a need to implement it on a target device or FPGA. It is a powerful tool use to design any mathematical model very easily and check there result. HDL coder one can convert. If inverted output of D flip-flop is connected to its input how the flip-flop behaves? Design a circuit to divide input frequency by 2? Design a divide by two counter using D-Latch. What are the different types of adder implementation?

Draw a Transmission Gate-based D-Latch? Give the truth table for a Half Adder. Give a gate level implementation of the same. Design an OR gate from 2: Design a D Flip-Flop from two latches. Design a 2 bit counter using D Flip-Flop.

What are the two types of delays in any digital system Design a Transparent Latch using a 2: What is metastable state? How does it occur? Design a D and T flip flop using 2: D esign D Latch from SR flip-flop.

What is race condition? How to avoid it? Design a 4 bit Gray Counter? Design 4-bit synchronous counter, asynchronous counter? Design a 16 byte asynchronous FIFO? Which one is good: Design a simple circuit based on combinational logic to double the output frequency. What is the difference between flip-flop and latch?

Give two ways of converting a two input NAND gate to an inverter? What is the difference between mealy and moore What is the difference between latch based design and flip-flop based design? What is metastability and how to prevent it? Why are most interrupts active low? How do you detect if two 8-bit signals are same? After how many clock cycles will it return to the initial state? How will you implement a full subtractor from a full adder?

In a 3-bit Johnson's counter what are the unused states? What is an LFSR? List a few of its industry applications. Implement the following circuits: Design a D-latch using a using 2: How to implement a Master Slave flip flop using a 2 to 1 mux?

How many 2 input xor's are needed to inplement 16 input parity generator? Convert xor gate to buffer and inverter. Difference between onehot and binary encoding? What are different ways to synchronize between two clock domains?

How to calculate maximum operating frequency? How to find out longest path? How to achieve degree exact phase shift? Tell some of applications of buffer?Efficient Implementation & Comparison of Signed Complex Multiplier on FPGA using FFT Algorithm Archana Fande1, Anil Sahu2 1ME IV Sem, Department of ET&T, FET, SSTC, Bhilai ADDER & SUBTRACTOR MODULE The output data is in the form of real and imaginary form which is separated by data distributer by using.
