Matched filter in the frequency domain
(1.5) (a) Consider the signal s(t) in 3(c). Assuming that the unit of time is a millisecond
and the desired frequency resolution is 1 Hz, use the function contFT to compute
and plot |S(f).
(b) Use the function contFT to compute and plot the magnitude of the Fourier trans-
form of the convolution s * SMF numerically computed in 3(d). Also plot for
comparison |S(f)12, using the output of 5(a). The two plots should match.
(c) Plot the phase of the Fourier transform of s✶ SMF obtained in 5(b). Comment on
whether the plot matches your expectations.

cm.
f=2 MHz

po 1 MPa (source pressure)
x=10 cm (propagates in a Newtonian fluid for 10 cm as a plane wave-not a sound beam)
a=0.5 dB/(MHz cm)
Consider 3 types of waves: sine, square, and sawtooth. (square and sawtooth only for grad
students)
Observe your plots and draw some conclusions. Discuss any possible issues you encounter.
2. (20 pts) We have the following 3 ultrasonic transducers:
a. Focused 1 MHz, 2.54 cm diameter, 5.08 cm focus
b. Focused 3 MHz, 2.54 cm diameter, 5.08 cm focus
c. Unfocused 0.1 MHz, 2.54 cm diameter
The transducers are operating in water (c=1486 m/s).
I. Plot the axial field for all transducers
II. Plot the focal transverse field for the focused transducers and the transverse field at the
Rayleigh distance (R_0) and at 2R_0 for the unfocused.
III. Assume source pressure of 0.1 MPa, and find the acoustic pressure in MPa at the location
