PURPOSE:To minimize the leak of the pulse to the output as well as to increase the dynamic range at the cut-off time by securing the gate switching with a small-amplitude pulse, and thus to enhance the frequency characteristic. CONSTITUTION:When the noise is added to input signal S1, pulse signal P is applied to first gate 6. Then gate 6 is turned ON and second gate 7 is turned OFF, thus eliminating the noise. Limiter 8 functions to keep the potential of A less than the potential of B. As a rusult, the normal operation can be insured for the second gate. |
