In the Case Study of Section 1.4, an antenna azimuth angle is controlled, and its corresponding block diagram is shown in Figure 1.8(d) in the text. There, the sensor used to measure the antenna’s azimuth angle is a potentiometer.

a. Modify the block diagram if the sensor used to measure the antenna’s angle is an accelerometer.

b. Modify the block diagram if the sensor used to measure the antenna’s angle is a gyroscope.
