Abstract
1,108,448. Function generator. NORTH AMERICA AVIATION Inc. 7 May, 1965, No. 19437/65. Heading G4G. [Also in Divisions G1 and H3] In a redundancy arrangement which provides improved reliability three or more signal channels are provided, each responsive to the same electrical or other input signal to translate it into an electrical output signal in accordance with a predetermined law. The outputs are connected in common to an output terminal, each channel being provided with an electrical feedback path individual thereto and established between the common output terminal and an intermediate point in the channel. In one embodiment the input of each of three phasereversing amplifiers 15 is connected via a corresponding input network comprising a resistor 16 shunted by a signal-shaping network 18, 20, to a common input terminal 12, while the output is connected via a resistor 13 to the common output terminal 14. Negative feedback is applied from output terminal 14 to the input of each of the amplifiers 15 via individual feedback resistors 17, shunted by signal-shaping capacitors 19 and resistors 20. The Specification includes a mathematical exposition demonstrating that the overall gain is unaffected by open or short-circuit failure of the resistors, and also describes arrangements in which the input comprises a mechanical force (Figs. 2, 3, not shown) and one in which a number of like stages are arranged in cascade (Fig. 4, not shown).
