ABSTRACT:
In a logic circuit, a transistor performs the function of a binary switching device and is controlled by the currents applied to the base thereof through differently weighted resistors. The resistors are connected to inputs to which signals representing different binary variables can be applied. The base of the transistor is also connected to a source of voltage through a variable resistor. By varying the value of the variable resistor, the logical function performed by the gate can be varied.
