Perform an internet information search on the terms “Bipolar Junction Transistors” (or “BJT”) and “MOSFET”. Extract relevant information and write a ONE-PAGE explanation on how one can use such devices for building amplifiers and digital logic switches (or “gates”). Which device, BJT or MOSFET, is more suitable for ultra-low power applications? What is the main reason?

Using MATLAB, determine whether the system below are a) linear/non-linear b) time-invariant/timevariant, c) causal/noncausal, d) has memory/memoryless:

y(t) = x(t) + x(t -1)

Provide MATLAB code and graphs to show your work for the linearity and time-invariance testing.

Assuming that we have a 66/11-kV primary substation with three 66/11-kV, 20MVA (rating of each transformer), power transformers, then the installed capacity is 60MVA and the firm capacity is 48MVA. I'd like to know what is the difference between installed and firm capacity. Furthermore, how was the firm capacity calculated from the installed capacity? What I know is that the firm capacity is calculated as follow: Firm Capacity = 20 + 20 + 4 + 4 = 48MVA, and that the equation (n - 1)x120% is used, where n is the no. of transformers.

Write a MATLAB function [p, z] = proj(A,b) that computes the projection of b onto the Column Space of an m × n matrix A. Your program should allow for the possibility that the columns of A are not linearly independent. In order for the program to work, you will need to create a basis for Col A.

What are the three main components of an operating system? And why?

A 120VAC fan is to be controlled by an MSP430F2273. Assuming the maximum

fan current is 2A, provide a solid-state relay interface using a Sharp

S108T02. Verify both voltage and current compatibility in the control interface.

Add a single push-button interface to the system and a status LED to be lit when the fan is ON. Provide a short program to toggle the fan with the

push-button.

An embedded system incorporates an MSP430F2274 clocked by a 4.096MHz
at 3.3V, driving two seven-segment displays and two discrete LEDs. The sevensegment
display draws 7.5mA per segment at 1.8V and the discrete LEDs
operate with 10mA each at 1.6V. Three push-buttons are needed for completing
the user interface. Design a suitable interface to connect all LEDs,
seven-segments, and push-buttons. Estimate the circuit power requirements
and recommend a non-regulated power supply and a suitable regulator.

why does the starting capacitor has dual values 100/130 or values in a range whereas the running capacitor has only one value?In starting capacitor which value should be consider in designing higher value or lower value?
