| Abstract: | Design method of Bessel low pass filter (LPF) used in direct digital synthesizer is introducde. This paper introduces the principle of direct digital synthesizing signals and analyzes the frequency spectra of synthesized signals. The design method of Bessel LPF and the circuit schematics and characteristic figures of the designed filter are presented in this paper. |
