(b) A new digital logic family, Schottky Barrier Logic (SBL), operates from a 5 V supply and has the following operational conditions: Vo-1.0 V, (i) Determine the worst case noise margin necting SBL to SBL (2 marks) (ii) Determine whether or not it is possible to directly connect TTL to SBL (i.e. TTL output to SBL input) (3 marks) (ii) Determine whether or not it is possible to directly connect SBL to TTL (i.e. SBL output to TTL input). (3 marks) (ii) If either (or both) of your conclusion to (ii) and (ii) is "no", suggest a method by which the connection might be made
