Abstract This paper proposes a study with signal to noise ratio (SNR), sampling frequency and system parameters because of the no-clear influence factors of the frequency locked loop (FLL) based on stochastic resonance (SR). Firstly, basic principle of FLL based on SR is simply interpreted and a simulation platform is set up. Secondly, through changing signal to noise ratio and sampling frequency and system parameters, the influence that they brings out is gradually clear. Finally, some meaningful conclusions are carried out. The tracking performance gets poor with the SNR declining, and the limit of SNR is E b /N 0 = 1 dB. The sampling frequency must be set 50 times higher than the frequency of signal, and the changing of sampling frequency has little effect on the improvement of tracking performance. System parameters are the critical factors that influencing the performance of FLL based on stochastic resonance, and it presents as an alternative numerical interval. The three key factors must be deliberated before designing and using the FLL based on SR.
