1.80 mm and a frequency of 115 per minute. (a) Find the maximum linear speed of the heart wall. Suppose the motion detector in contact with the mother’s abdomen produces sound at 2 000 000.0 Hz, which travels through tissue at 1.50 km/s. (b) Find the maximum frequency at which sound arrives at the wall of the baby’s heart.

The relative response from ‘Equivalent reflectors’ of different sizes at different distances can be predicted mathematically from the probe effective diameter, frequency and near field length (a function of the first two). Probe sensitivity can be calibrated from a single measurement (usually the back wall echo) DGS/AVG has several limitations:
