| Abstract: | A high-accuracy measuring technique is presented for detection of tiny signal's frequency and amplitude by digital signal processing and virtual instrument technology.With this technique, such functions as feedback-sampling frequency design,self-adaption digital filter and digital phase sensitive detection are accomplished in this system.Besides the detection of the signal's phase and amplitude,its harmonic wave can also be accurately measured by this technique. |
