NPN Transistor Switching Circuit Before starting with the circuit diagram, you should know the concept of NPN transistor as a switch. In an NPN transistor, Current starts flowing from collector to ...

A computer program, which has a Boolean expression and a functionally complete set of switching functions as input data and as output data, gives a description of a logic diagram that shows the ...

This paper describes an IBM 7090 program for the design of single output combinational switching circuits for arbitrary sets of primitive logical elements. The only restriction on circuit ...
