Question
A chemical plant needs a microprocessor-driven alarm system to warnof critical conditions in one of its chemical tanks. Thethank has four HIGH/LOW (1/0) switches that monitor temperature(T), pressure (P), fluid (F), and weight (W). The alarm (A)will activate when any of the following conditions are met1. High fluid level, high temperature, high pressure. 2. low fluid level, high temperature, high weight. 3. low fluid level,low temperature, high pressure. 4. low fluid level, low weight, high temperature.
A) Show the truth table of this function. B) Write the logic equation for this function. DO NOTsimplify the equation.
