专利汇可以提供Eliminating circuit of pulse noise专利检索,专利查询,专利分析的服务。并且PURPOSE:To decrease the distorition to the high region frequency when the noise eliminating circuit is in operation, by sectioning the input signal into two systems, and taking one for normal signal transmission path and another for signal level holding circuit. CONSTITUTION:When the pulse noise detection output VC is at low level, the differential transistrors Q3, Q10 are turned on. Accordingly, the transistor Q1 being the wsitch is on. The 1st input signal is transmitted to the output terminal OUT via the transistor Q9 being the first switch Q1. Since no capacitor is included in the transmission path, the high region distortion is not deteriorated. When the pulsive noise detection output VC is at high level, the 1st switch Q1 and 2nd switch Q9 are off and the signal of the level held at the capacitor C is obtained via the transistor Q3 being the 3rd switch.,下面是Eliminating circuit of pulse noise专利的具体信息内容。
