First–order accurate monotone conservative schemes have goodconvergence and stability properties, and thus play a veryimportant role in designing modern high resolution shock-capturingschemes.Do the monotone difference approximations alwaysgive a good numerical solution in sense of monotonicity preservationor suppression of oscillations? This note will investigate this problemfrom a numerical point of view and show thata (2K+1)-point monotone scheme may give an oscillatory solutioneven though the approximate solution is total variation diminishing, andsatisfies maximum principle as well as discrete entropy inequality.
