PURPOSE: A discrete time receiver is provided to have an efficient and wide dynamic range which can be corresponded to an input signal having a broadband frequency. CONSTITUTION: According to a sampling clock, a sampling mixer(110) performs the sampling of an input signal. Using a control signal, a discrete time filter(140) controls a decimation ratio. The discrete time filter filters the sampled signal with the usage of the filter clock. A clock generator(130) creates the sampling clock provided to the sampling mixer. The clock generator creates the control signal and the filter clock with comparison between the frequency of the sampling clock and a set output frequency.
