Chapter 5, Problem 5.70P
Interpretation Introduction

Interpretation:

The composition of Cu-Zn alloy is nonuniform during freezing of a Cu-Zn alloy. If an alloy is heated to 6000C for 3 h, the composition becomes uniform due to the diffusion of zinc. The temperature required if this homogenization treatment in performed for 30 minutes needs to be determined.

Concept introduction:

Fick's second law is represented as follows:

cscxcsc0=erf(x2DTt)

Here,

Cs = Constant concentration of diffusion atom.

Cx = Diffusion concentration of atom at location X

Co = Initial concentration of diffusion of atom.

t = time required.

D = Diffusion coefficient.

X = Carbon diffuses in 'cm'.

Q-Draw a sample and hold electronic circuit using op-amp then explain its operation. I hope the solution is from a human being and not from intelligence
The  ALU for bit 31  shown in the image supported the set on less than (slt) instruction using just the sign bit of Result31. Try this operation on the decimal values a = -7 and b = 6, using a 4-bit, 2's complement representation. Show that this example produces an incorrect value of the Set output. Therefore the Overflow output must also be used to compute Set. Modify ALU31 to handle slt correctly. Show your design on a copy of the figure.
Design an AC-coupled (input and output)  amplifier with a gain of -8 which has identical 3 dB corner frequencies of 10 kHz for high pass coupling at the input and output. Assume a power supply of 5 volts.
