  The radio pulse from a pulsar can be temporally broadened by multipath
scattering in the interstellar medium and by instrumental effects within the
radio telescope. The observed pulse shape is a convolution of the intrinsic one
with the impulse responses of the scattering medium and instrumentation. Until
recently, common methods used to model the observed shape make assumptions
regarding the intrinsic pulse shape and impulse responses, compute the
convolution numerically, and solve for the pulse width and scattering timescale
iteratively. An analytical solution is shown to exist for the specific case of
the temporal broadening of a Gaussian-shaped pulse by a thin scattering screen.
The solution is applied to multi-frequency observations of PSR B1834-10 to
characterize the frequency dependence of its intrinsic pulse width and
scattering timescale.
