The objective of this lab is to practice your Verilog coding and the design of a Finite State Machine. Lab Goal: For this lab, you will code a Verilog module to implement the FSM described in this document. This lab will also require that you use the Seven - Segment Display on the DE0 - CV FPGA board. Design Specifications for the FSM Implem ent the following simple state machine on the DE0 - CV FPGA board. This FSM will have 5 states. The clock to this FSM will be provided by yourself using KEY0 (one of the push buttons on the board). Include a debounce module in your code but do not use it. S o you write the code as described in the lecture, but there should be no debounce module instance. I want you to understand this module but it is unnecessary on our board. The transitions from any one state to another are determined by switches 0 through 4 of the board (SW0, SW1, SW2, SW3, and SW4) as shown in the state diagram below. This will be easier than using pushbuttons for the inputs to switch to states. That means you set the switch and then clock it using KEY0. It really only matters what the swi t ch positions are when the clock edge occurs. NOTE reiterating this use slide s witches not pushbuttons for input. Use KEY0 for the clock, and generate the clock signal by hand by pushing KEY0. Any input transition not explicitly referenced in the diagram keeps the machine in the same state. Moreover, if two or more switches are asserted simultaneous ly, no transition should occur. SW0 acts as the rese t and should reset the FSM to S 00 regardless of all other switches or the pushbutton. (note you could use K EY1 pushbutton instead but it isn’t clear that would be better). How to write your code: Study Lecture 9 section 3 on how to write a Finite State Machine in Verilog. Your code will have two parts. There will be a synchronous part which is the part models the flip flops. An example of this is Lecture 9 slide 33. The other part is the combinatorial part, which is the part that feeds the inputs to the flip flops, that is like the code in Lecture 9 slides 29 through 32. This i

a) Sketch the symbols and show the respective equations to represent an adder, multiplier, delay, and memory.

b) Determine the Fourier Transform and Inverse Fourier Transform for an arbitrary periodic and aperiodic signal.

Discuss the process by which distribution network service providers undertake network investments in the NEM, and opportunities for demand-side options within this framework. ?200 words)

In a liquid transmission pipeline, a pump had been designed for a throughput of 10,000 bpd. However the demand has increased by 25%. It has been proposed to increase the impeller diameter and speed in order to meet the new demand. However, the impeller diameter increase is limited to10%. The original speed of the pump is 1200 rpm and the original power is 60 kW. Calculate A. The new speed of the pump. B. The new shaft power of the pump.

Develop a detailed model the inverted pendulum system in MatLab/Simulink (a feedback compensator to stabilise and control the dynamics of a rotating inverted pendulum, as described in Microchip Application Note AN964, “Software PID Control of an Inverted Pendulum Using the PIC16F684” by Charais and Lourens.

I am supposed to do a communication systems project including MATLAB. Topic maybe something related to for example OFDM system, AMR reading using gprs etc. Or any communication systems related topic.

Can some one provide with the brief project description and MATLAB code?
