An industrial soft drink production plant needs to implement a quality control system for its bottling line. The system must monitor four critical parameters and activate different alarms depending on the conditions detected. Design a digital circuit with 4 inputs and 3 outputs for this purpose,
Design the logic circuit for this control system using Karnaugh maps to simplify the Boolean functions of each output. The final design must be efficient and use as few logic gates as possible.
Inputs:
A: Carbonation level (0 = normal, 1 = high)
B: Liquid temperature (0 = normal, 1 = elevated)
C: Line pressure (0 = normal, 1 = low)
D: Filling speed (0 = normal, 1 = low)
Outputs:
X: Minor adjustment alarm (triggered when an odd number of parameters are out of range)
Y: Major revision alarm (triggered when at least three parameters are out of range)
Z: Adjacent parameters alarm (triggered when exactly two adjacent parameters are out of range)
Please solve it for STS and TST
