Designs a linear phase FIR lowpass filter such that it: - minimizes the maximum passband ripple - has a constraint on the maximum stopband attenuation( This is a convex problem. minimize delta s.t. 1/delta <= H(w) <= delta for w in the passband |H(w)| <= atten_level for w in the stopband where H is the frequency response function and variables are delta and h (the filter impulse response). )

正弦周期信号的随机共振，不同于以往微弱信号检测中的抑制噪声，随机共振能通过噪声加强信号传输能力( We present the numerical method to solve the bistable SR model based on Runge-Kutta algorithm, and propose a new kind of approach for detecting weak signal, which can effectively detect both period and aperiodic weak signals corrupted by the strong noise background. )
