| Abstract: | In this paper,the principle of digital averaging algorithm is analyzed and it is simulated and verified by LabVIEW. The simulation result shows that the digital averaging algorithm has good waveform restoration ability for the weak signal. After by adding and averaging for N times, the signal to noise ratio of output signal can be increased for 101gN dB. |
