Question details

FIGURE 3.36 System for Problems 3.10 and 3.14 24 Q8 3.10 A tank shown in Figure 3.36 has the following Boolean variabies: flow rates, QA, OB, and QC, pressure, P; and level, L. All are high if the variable is high and low otherwise. Devise Boolean equations for two alarm conditions as follows: a. OV overfill alarm 1. If either input flow rate is high while the output flow rate is low, the pressure is low and the level is high. 2. [If both input flow rates are high while the output flow rate is low and the pressure is low.] b. EP empty alarm 1. If both input flow rates are low, the level is low and the output flow rate is high 2. If either input flow rate is low, the output flow rate is high and the pressure is high 3.11 Devise logic circuits using NAND/NOR logic that will provide the two alarms of Problem 3.10. Section 3.3 3.12 A sensor provides temperature data as 360 v/c. Develop a comparator circuit that goes high when the temperature reaches 530°C 3.13 A light level is to trigger a comparator high (5 V) when the intensity reaches 30 W/m2. Intensity is converted to voltage according to a transfer function of 0.04 V/(W/m2). Noise is found to contribute +1.6 W/m2 of intensity fluctua- tions. Develop a hysteresis comparator to provide the required output and immu- nity for noise. Sensors are available for the system shown in Figure 3.36 that provide voltage out- puts with the following transfer functions Flow rate%-0.15VO (Q in gal/min) 3.14 20 Pressure: Vppin psi) Level: V 0.05L (L in meters)
