Objective: The assignment is intended to enhance students MATLAB stills and to employ the software to solve issues related to signals and systems.
A student is expected to be able to graph various signals. find and graph the convolution of two signals. find the Fourier transform and other signals & system related topics using MATLAB.
Question 1 Graph the following functions:
(a) g(t) = -4 ramp(t) u(t - 2).
(b) g(t) = 3 rect(t/4) - 6 rect(t/2).
Qnestion 2: A periodic signal x(t). with fundamental period To = 6. is described over the time period 0 < t < 6 by
rect (t-2/3)-4rest(t-4/2)
What is the average signal power of this signal?
Question 3:
Graph the signal: g[n] = u[5n].
Question 4, Graph the original below function and the scaled function.

Question 6 Use MATLAB to find, and to graph. the unit-sequence response of the system displayed below.
Question 7 A periodic signal x(t) with a fundamental period of 2 seconds is described over one fundamental period by
Graph the signal. Then, graph on the same scale the signal xN(t) given by
For N = 10, 20 and 30 (In each case the time scale of the graph should cover at least two fundamental periods of the original signal).
Question 8 A signal is defined by x[n] = sinc(n/8). Graph the magnitude and phase of the DTFT of x[n - 2].

Compute the amount of solution used from the buret
: 2 students are titrating and started the titration at 30.0 mL. The buret was at 49.50 mL and the solution still had not chnaged to the base color. They stopped, now at 49.80 mL and refilled the buret to 0.00 mL and continued to titrate.
