Explain PLA with a block diagram.

A combinational circuit is defined by the functions:

F\(A,B,C) = ೫(3,5,6,7)

F2(A,B,C) = £(0,2,4,7)

Implement the circuit with a PLA having three inputs, four product terms and
two outputs.

Draw a flow chart and explain the addition and subtraction of two binary
numbers in signed magnitude representation.

Differentiate between synchronous and asynchronous counters.

Draw the circuit diagram of a 4- bit binary ripple counter and explain its

working.
