Abstract

We analyse the behaviour of the exponential sampling series SwχfS_{w}^{\chi}f at jump discontinuity of the bounded signal f.f. We obtain a representation lemma that is used for analysing the series SwχfS_{w}^{\chi}f and we establish approximation of jump discontinuity functions by the series Swχf.S_{w}^{\chi}f. The rate of approximation of the exponential sampling series SwχfS_{w}^{\chi}f is obtained in terms of logarithmic modulus of continuity of functions and the round-off and time-jitter errors are also studied. Finally we give some graphical representation of approximation of discontinuous functions by SwχfS_{w}^{\chi}f using suitable kernels.
