Logic for computer science(lec 5)Combinational Logic
Types of logic circuits3/11/2016By:-Gourav KottawarThere are two types of logic circuitsCombinational CircuitsFormed by combination of different logic circuitsOutputs depend on the current inputsEx- Multiplexer, De multiplexer, Encoder,DecoderNo memory allocation requiredSequential CircuitsOutputs depend on current and previous inputsRequires separating previous, current and futureCalledstates or tokensExample: Finite State Machines (FSMs),Pipelines
Difference between Combinational andsequential circuits3/11/2016By:-Gourav KottawarCombinationalSequentialOutput of any instance of timedepends only upon the inputvariablesOutput is generated dependentupon the present input variablesand also on the basis of pasthistory of these inputsMemory unit is not required. i.e.it doesn’t allocate anymemoryto the elements.Memory unit is required. . i.e. itallocates any memory to theelements.
