An amplifier with an output impedance of 75 ? is connected to a filter with a characteristic impedance of 60 – 20j ?. Design a single shunt stub matching network using an open circuit for a frequency of 500 MHz. Show ALL calculations. a) Calculate the normalized load admittance. b) Determine the distance (in ?) to the stub in the direction of the generator. c) Determine the normalized input admittance of the stub. d) Calculate the susceptance of the stub. e) Calculate the length of the short circuit stub. f) Determine the standing wave ratio (SWR) for the normalized admittance point. g) Sketch the layout of the system, indicating the distance to and the length of the stub

How would I code the following in assembly language?

Use the Keil programming environment to code the C8051F330 SiLabs 8051 micro controller. All the documentation is available on efundi. The program shall be done in assembler and you shall use the DJNZ instruction to generate a delay time to flash the LED. The LED shall flash in the following sequence:

1. On for 50mS,

2. Off for 400mS,

3. On for 50mS,

4. Off for 1.5S,

5. Repeat the sequence from step 1.

Consider the Characteristics of Design Thinkers. Which of these characteristics describe you? Give an example of how you used those skills in the past.

WHAT ARE THE DIFFERENCES BETWEEN TCP/IP AND UDP IN TERMS OF OSI LAYERS AND DEFINITION ITSELF?

PLEASE GIVE BREIFE EXPLANATIONS WITH PICTURES AND EXAMPLES WITH EASY ENOUGH TO MEMORIZE AND UNDERSTAND

Two arrays “Array1” and “Array2” are given with 25 words each. Design an ARM assembly code to compare sum of the numbers sotred in the arrays. If sum of Array1 is greater, save a “1” in R10, otherwise, save “0’ in R10.

As for protection relays and overcurrent. Why do we have to inform which specific norm to the use of its curve of actuation ?

Discuss what is meant by line and load regulation. Should they be high or low if you want a quality power supply?

Discuss the differences between a shunt regulator and series regulator and how each works.

PLEASE NO HAND WRITTING

Write a project proposal on the topic Power Electronics Converters for Wind Turbine Systems

Write a VHDL code for a 4-bit comparator which takes two 4-bit input values and (0.5) determines whether the numbers are equal. 2. 2. Write a structural VHDL code to implement the circuit of Fig. 2, using the components (0.5) developed in 1.3 and 2.1. 2. 3. Write a VHDL test bench for the above and verify by simulation. (0.5) 2. 4. Implement the design in an FPGA (Note: You may need a `clock manager' to reduce (1.0) the clock frequency).

Research on zero-point energy perpetual motion machines. Decide if designing such machines is possible or not possible and explain your reasoning. Bear in mind that these perpetual motion machines may be nanomachines.

Let’s say we live in a country that gets very cold, in Northern America / Europe. In winter, we monitor the outside temperature, so that heaters can be switched on, inside the house. The idea is that, the colder it is outside, the warmer it should be inside. The heating side of things is just a heater that is either switched on, or switched off. Just from the information that has been given, please discuss this matter in depth. Provide reference to OPEN / CLOSED loop control, FEEDFORWARD / FEEDBACK control and MODULATING / ON_OFF control raised in the discussion.

Explain why.

Is Fourier Series can represent any normal, periodic function if we use enough sinusoid term?

For the system with transfer function H(s)=1/(s-2)(s-1) determine the ROC for stability.
