摘　　要：提出了一种调制解调式双二次 (托氏电路 )滤波器 ,它可直接对以方波为载波的基带信号 (方波的幅度信号 )进行带通滤波、低通滤波处理。尤其 ,作为基带信号的带通滤波可在载波频率上实现级联运用。The paper gives a modulating-demodulating type biquadratic (Tow-Circuit) filter. That is a band-pass filter or a low-pass filter to process direct baseband signal (amplitude of square-wave) whose carrier is the square-wave. As a band-pass filter it may be cascaded before demodulation.
