A Precision Non-Linear Analog Transfer Function Generator
A technique for generating driving waveforms having non-linear dependence on an independent variable is described. Forward biased high-conductance silicon diodes are used as feedback elements in an operational amplifier circuit. A FORTRAN time-sharing computer program has been written and used to aid in the selection of circuit components. A radio frequency program generator has been designed and built to provide the drive to a voltage-controlled oscillator as a function of the NAL main accelerator bend magnet current.
