User's guide to the DCON deconvolution code. [For 7600]

Technical Report ·
OSTI ID:6130333
DCON is a 7600 code that uses Fourier transform techniques to solve the convolution equation S(t) = R(t)*I(t), where the * stands for the integral convolution operator. S is the output signal, R, the response function, and I, the input signal. For example, I might be the input to some linear physical system whose impulse response is R. Then S(t) will be the output of the system. The basic purpose of the code is to find I(t), given S(t) and R(t). One may also actually know the input and output signals and wish to find the impulse response. Because real data are always noisy, and deconvolution tends to greatly amplify noise, considerable attention was given to various filtering schemes and ways of limiting the bandwidth over which the deconvolution takes place. This feature makes the code practical, and allows one to quantify exactly what (in terms of smoothing, bandwidth, etc.) has been done to the measured data to allow deconvolution. The various filtering options are explained. The various switches to the user allow the code to be used to convolve two functions, filter a function, or just obtain its spectral representation. Output can be obtained in the form of graphs and SOCKITTOME files. (RWR)
