The present invention discloses a wave reduction sampling method of signal output. The method includes smoothing the original digital signal at a host terminal to rebuild a simulating signal, and sampling the simulating signal with a sampling rate to obtain a reductive signal. The sampling rate is an operating frequency of an audio/image outputting apparatus divided by a transmission multiple value. The claimed invention transfers the sampling rate by software at the host terminal to reduce the signal to output, and has advantages of having flexible outputting frequency, being suitable to any operating frequency, omitting the clock synthesizer and reducing the cost.
