Show that the Boolean equation
A · B + A · (A · B)‾
reduces to A. 8 A process involves moving speed, load weight, and rate of loading in a conveyor system. The variables are provided as high (1) and low (0) levels for digital control. An alarm should be initiated whenever any of the following occur:
a. Speed is low; both weight and loading rate are high.
b. Speed is high; loading rate is low. Find a Boolean equation describing the required alarm output. Let the variables be S for speed, W for weight, and R for loading rate.
