Now accounting for attenuation and reflection/transmittance at interfaces calculate the
actual amplitudes of the pulses from interfaces A and B relative to the incident
amplitude.

Using the table above and in the figure shown below, the transducer is stimulated with a
short pulse resulting in a short burst of pressure traveling through the sequence of materials
shown in figure. Assume that no echoes are returned at the transducer-tissue interface. The
transducer is operating at 3 MHz frequency, measured from the transducer edge, A 3 cm
and B= 5 cm. Use specific sound speeds in the corresponding materials.
a) Assuming perpendicular incidence and that the system is setup to equalize the amplitude
of all the returned signals (don't account for attenuation and reflection/transmittance at
interfaces), sketch the timing of the first echoes (signals) received by the transducer
from interfaces A, and B.
