Design an ECG amplifier using 3 operational amplifiers for standard (AHA) specifications.

What is the importance of measuring current in the clockwise direction?

In this exercise, you will be given a system with their input/output relationships. Using MATLAB, determine whether the system below are a) linear/non-linear b) time-invariant/timevariant, c) causal/noncausal, d) has memory/memoryless:

y[n] = x²[n]

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

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.
