Computer compensation for cable signal degradations

This paper describes two techniques for computing software cable compensation filters. These filters are used in correcting waveforms recorded from diagnostics on pulsed power accelerator. Applicable topics in continuous and discrete linear systems theory are reviewed. The first technique for computing a compensation function consists of recursively solving a discrete time domain convolution equation using measured undegraded and cable degraded pulses. The second tecnique computes the compensation function in the frequency domain using an analytical model of the cable frequency response and a constrained inverse filter. Detailed procedurs are described for computing cable compensation filters using an interactive data manipulation and hardware control program. 6 refs., 24 figs.
