Abstract

J. H. T., G. K. T. E. . Correcting for the dynamic response response. In this paper we establish the theoretical basis investigate the limitations the method used by Arieli Van Liew. We also correct MS measurements with a method known as Wiener filtering, which is based on Fourier transforms is routinely applied to similar problems in image processing (4). METHODS filter gave the most accurate s in all cases examined. impulse response; step response; convolution; numerical Wiener filter; delay; We define an actual gas concentration signal as the true signal. The MS makes a measurement the true signal responds to give what we call the measured signal. If the response the MS is linear obeys the principle superposition then the measured signal is related to the true sicnal by the convolution integral (3) thus t h(t) --oo g(u)f(t - 4 du (1) s where g(t) is the true signal, h(t) is the measured signal, f(t) is the impulse response the MS. The impulse response is simply the measured signal that would be obtained if the true signal were an impulse (an infinitesimally narrow peak with area unity) is a useful function for characterizing the instrument, since it
