    • An oversampling circuit and a digital/analog converter which have small circuit scales and the component costs of which are reduced. Data inputted at predetermined intervals is multiplied by four multiplicators by means of a multiplier (1), and the multiplication results are held cyclically in data holding sections (2-1 to 2-4). Data selectors (3-1 to 3-4) read out the data held in the respective data holding sections (2-1 to 2-4) in a predetermined order and output predetermined step functions. Oversampling is carried out by generating step functions corresponding to the respective data sets inputted sequentially at different timing, digitally integrating each step function twice by means of integrating sections (4-1 to 4-4), summing the integrated step functions, and thereby increasing the sampling frequency pseudoly for each input digital data set.
