Unformatted text preview: s s 1 s 2 MSB LSB Problem 2: Consider the pair of logic functions: f = ( a + bc + bcd ) e f 1 = ( a + bc + b cd ) e ( a ) Show how these can be implemented using a PLA(without external logic). Indicate: The number of inputs ( n ), the number of product terms (AND gates, p ), and the number of outputs, m . Draw a diagram of the PLA, using the abbreviated form in which a single wire connects to the ANDand ORgates’ inputs. ( b ) Explain why a PAL would be less suitable than a PLA for the pair of functions above. 1 Problem 3: The diagram below is for a PLA. a b c d f 2 f 1 f ( a ) One of the outputs appears to be a mistake. Which one, and why? ( b ) Write a Boolean expression for each output. ( c ) Draw a logic diagram showing only the gates that are needed. 2...
