Plot the absorption mode signal of a Lorentzian line as a
function of frequency for w=100 hz, and three values T2 equal to
1.0 sec, 0.3 sec, and 1.0 sec. How is the full width of the peak
related to the value of T2?
Sampling 2 periods of each signal in
(below) with 100 samples and plot the signal with respect to the
same frequency reference signal cos(ω0t):
a.xa(t)=50sin(100t+0.2)
b.xb(t)=25cos(5000t−π/4)
c.xc(t)=50sin(1000t+
π/4)−20cos(1000t−0.5)
d.xd(t)=30sin(3000(t−5×10−5))
e.xe(t)=25cos(5000t−2.25π)
f.xf(t)=−25cos(5000t+3π/4)
A plot of detector signal versus ppm Ca2+ yielded a
best fit straight line with a slope of 1.38 volts/ppm. Multiple
blank measurements resulted in a standard deviation of 0.18 volts.
Using a 2:1 signal-to-noise ratio criteria, calculate the detection
limit for Ca2+ in ppm when this method is employed.
Thanks!

1. Generate a sine wave with frequency 100 Hz.
a. Sample the signal with a sampling frequency (i) 1000 Hz and
(ii) 1050 Hz.
b. For each frequency in Question 1(a), perform
DFT for ONE (1) cycle and ONE and a HALF
(1.5) cycles of the waveform. Comment on your
observation.
The parallel-plate waveguide is air-filled and a = 2 cm.
Plot the frequency as a function of the longitudinal propagation
constant for TM2, numerically find and then plot the phase velocity
and the group velocity as a function of the longitudinal
propagation constant. Use a range of the longitudinal propagation
constant from 0 to 1000 [m-1]. In all graphs indicate the light
lines.
I will give thumbs up! please include detailed
plots
there is a sinusoidal message signal (f = 100 Hz).
Make amplitude modulation with carrier frequency of 10KHz. Use
three different modulation depths / indices (0.2 /0.60/0.8).
Then demodulate this mixed signal (for these three cases) by try
to get message signals. (need matlab codes and graphs)
Specify the aliasing frequency of a signal that has a maximum
frequency of 92kHz and a sample frequency of 130kHz. Is this an
optimal sampling frequency? If so, explain why? If not, propose an
optimal sampling frequency.
