(16 points) Consider a pulsed Doppler system, which operates at a center frequency of 7.5 MHz. This system is used to image blood flow in a vein located at a distance of 5 cm from the transducer. The angle between the beam and blood flow is 60°. Assume that the minimum velocity that this instrument can measure is 2 cm/s (FYI, this limit is typically imposed by tissue movement, but this information is not needed to solve the problem). If needed, please assume c = 1540 m/s. Please find: i) i the maximum velocity that this instrument can measure; ii) the minimum Doppler frequency; iii) the spectral broadening: iv) the pulse repetition frequency.
