| Abstract: | Proposed a design of Butterworth low pass filter, and simulated the circuit with the simulation software. The ampli-tude-frequency characteristic and phase frequency characteristics are perfect, within the pass-band frequency characteristic is flat, and there are no wave fluctuations, the curve changes slowly to zero inside the stop band, the index can meet the require-ments, can achieve better filtering effect. |
