Design, build and test a sensor that measures forearm rotation (pronation and supination)

Equipments: potentiometer
Goniometer
Tape,glue

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

PD CONTROL QUESTION

Is it possible that for PD controlled case following parameters are true?

I have a transfer function T(S)=.023/(.02913S^3+.1543s^2+.1205S). I need to design a PI, PD, or PID controller to give this system a peak overshoot PO of 15% and a rising time Tr of 3 seconds. I have equations that relate the characteristic equation to the PO and Tr, but that only works for a second order equation.

Consider a pMOS transistor with VTH = –0.5 V, Kp = 40μA/V2 , length, L = 0.25μm, and width, W = 1.25μm.

(a) Given that VSG = 1V, determine the range of values of VSD for which the device is in the saturation region.

(b) Given that VSG = 1V, determine the range of values of VSD for which the device is in the triode/linar region.

(c) Plot ISD vs VSG for operation in the saturation region. Ignore channel length modulation i.e. assume that λ = 0.

For the following parts, you will try to “bias” the transistor to meet your needs i.e. choose VSG and VSD. Assume length, L = 0.25μm, and width, W = 1.25μm.

(d) What VSG should you use such that the transistor is in saturation and ISD = 252μA? Assume that λ = 0.

(e) For VSG should you use that the transistor is in triode region and its ON resistance is ron = 3kΩ?
