Abstract

1,035,505. Transistor circuits. ELLIOT BROS. (LONDON) Ltd. July 24, 1964 [July 30, 1963], No. 30117/63. Heading H3T. A circuit more particularly for indicating whether a D.C. voltage V1 lies within a given range comprising two semi-conductor controlled current devices such as transistors VT1 and VT2 having an output circuit electrode connected in common to a point A at which the potential is dependent on the sum of the currents through the devices, an A.C. signal fed to one control electrode, whereby an A.C. output signal is available at an output of the other device if the voltage V1 lies within a range between which neither VT1 nor VT2 is cut off.
