For a single phase bridge rectifier, the source is 200Vrms/60sssHz. The load is 2000W. the winding
resistances of the transformer secondary is 0.5Ω and the forward drop resistance of each of the used
diodes is 0.2 Ω.
1. What would be the load resistance.
2. Calculate the following:
o TUF
o Rectifier power efficiency
o Rectification efficiency
o Input power factor
3. Simulate the circuit and show the following:
o Input and output voltage and current waveforms
o Diode current and voltage waveforms
4. Insert a 2?? capacitor in parallel to the output load and simulate the circuit again. Plot the
output voltage and current new waveforms. And find the new delivered power to the load from
simulation
5. Repeat part 4 but exchange the capacitor with a 0.5?? series inductor.

. Why a curved feedline will have less radiation? Explain.

Design a clipper circuit which will clip off the input above +5 V and below +2 V.

You may use any of the following components

1) Diodes with forward drop of 0.7V

2) Zener Diodes (Ideal) of any breakdown voltage

3) DC voltage source (any value)

(Please provide all steps in detail. I wish to study using them)

(9) When radiation interacts with a semiconductor resulting in stimulated emission, the

wavelength of the output radiation is (   )

(A) Half the wavelength of the incident radiation

(B) Two times the wavelength of the incident radiation

(C) May be higher or lower than that of the incident radiation, depending on the material

(D) Same as the wavelength of the incident radiation

Consider three different processors P1, P2, and P3 executing the same instruction set.

P1 has a 3 GHz clock rate and a CPI of 1.5.

P2 has a 2.5 GHz clock rate and a CPI of 1.0.

P3 has a 4.0 GHz clock rate and has a CPI of 2.2.

a. Which processor has the highest performance expressed in instructions per second?

b. If the processors each execute a program in 10 seconds, find the number of cycles and the number of instructions.

c. We are trying to reduce the execution time by 30%, but this leads to an increase of 20% in the CPI. What clock rate should we have to get this time reduction?

Could you please help me getting the idea ?

The discrete cosine transform (DCT) represents an image as a sum of sinusoids of varying magnitudes and frequencies. The functions of DCT computes the two-dimensional DCT of an image. The DCT has the property that, for a typical image, most of the visually significant information about the image is concentrated in just a few coefficients of the DCT. For this reason, the DCT is often used in image compression applications

i) Write a Matlab Program to obtain low bit rate block and compressed image quality using Discrete cosine transform (DCT) coding

ii) Detail each steps of compression and decompression and reduce the size to 8x8 non-overlapping blocks with DCT quantized coefficients for blocking artifacts by Matlab program.

iii) Highlight the results of reduced artifacts and validate the quality using PSNR value. Justify the result

Can someone please explain how to use superposition. also, to find the current please explain clearly how to use current dividers. I'll give it a like for the best response
