摘要： A programmable function generator, which is suitable for construction in integrated circuit form, includes a current ladder which produces an output voltage or current which is a programmable function of an input voltage or current at n evenly spaced values of the input voltage or current corresponding to n spaced output points along the current ladder. For values of the input signal between any two of the n values, the output is a linear interpolation between the output values at the corresponding output points along the current ladder. The programming of each point is independent of all other points, and the output at any point is established by the ratio of a resistor pair. Accurately controlled current sources or current drivers control the flow of currents to each of the n points and the flow of current from terminals of said current ladder including compensated current drivers, one of which differentially controls current flow from end terminals of the current ladder in response to a variable input control voltage or current which, for example may be a linear ramp of voltage or current.

摘要： A sawtooth generator provided with a device for generating a digital sawtooth function, said device being connected to a digital-to-analogue converter, also containing an integrator and an error voltage detector to convert differences occuring at discrete moments between the output voltage of the digital-toanalogue converter and the output voltage of the integrator to a control voltage varying in steps, which, fed to the integrator causes the output voltage of the integrator to form an approach of the function to be generated shaped as an angled line.

摘要： The invention relates to an apparatus for generating a mathematical function of the type y f(x) by linear interpolation between two values y1, y2 which are known for two values x1, x2. The apparatus includes two function generators respectively producing values y1, y2. Associated with each function generator is an interpolation function generator. The interpolation function generators produce, for a value of x lying between x1 and x2 signals corresponding to (x2-x)/(x2-x) and (x-x1)/(x2-x1) respectively.

摘要： A capacitive voltage divider arrangement for driving a position transducer. Individual ones of a first plurality of individual capacitor plates are respectively capacitively coupled to individual ones of a second like plurality of capacitance plate areas, the second plurality of capacitive areas being conductively connected together and varying in area from plate area to plate area. Individual ones of a third plurality of capacitance plate areas, which are conductively connected together, are likewise respectively capacitively coupled to individual ones of the first plurality of plates. The voltage distribution on a plurality of position sensing grid lines, individual ones of which are connected to respective individual ones of the first plurality of plates, varies in accordance with the varying in areas from plate area to plate area of the second plurality of plate areas.
