Abstract: We have developed a model that allows the calculation of time-dependent radiation in relativistic jets. Using this model, we have simulated multifrequency variability of the synchrotron and inverse Compton emission. Calculation of the latter uses integration over the population of relativistic electrons and the spectrum of the incident emission, which can be delayed due to light-travel time effects. The inclusion of the light-travel time effects for the synchrotron self-Compton (SSC) calculation and careful treatment of the evolving population of relativistic electrons yields a good fit to the March 1999 flare of 3C 273 (McHardy et al. in preparation), which had an unusual reverse time delay (infrared emission leads x-rays). The model fit determines the number density of relativistic electrons and the magnetic field strength in the source.
