The following three logic functions are required in a digital circuit. Determine the minimum number of AND terms required if these functions are to be implemented on a PLA logic

structure; (O Plot the connections required to implement these three logic functions on the input and output maps in Handout 2.(ii) (b)Describe what is meant by hazards in logic circuits and give an example of how it is possible for these to occur in logic circuits.(4 marks) (c) Explain the effect meta-stability has on logic design and explain how state machines can be designed in order to minimise this effect.(4 marks) (d) Identify all of the static 'l' and static '0' hazards present in a logic circuit described by the equation:(8 marks) F=(B+\bar{D}) \cdot(A+D)+\bar{A} \cdot \bar{C}
