Abstract

PURPOSE:To establish the pulse pick up filter which can obtain the pick up pulse in real time and not delayed. CONSTITUTION:The incoming pulse 6 is branched and inputted to the frequency discrimination circuit 1 and also to the first delay circuit 2a which performs compensation and delay by the time required for frequency discrimination. The pulse in matching with a given frequency range at the frequency discrimination circuit 1 produces the gate signal which passes through the pulse delayed in the first delay circuit 2a of the incoming pulse corresponding to the one shot circuit 4. The logical product circuit 5 passes through only the pulse in matching with the frequency, and this pasing pulse is inputted to the second delay circuit 2b. the sum of the delay time of the delay circuits 2a and 2b is set equally with the pulse repetitive time specified. The logical product between the output of the second delay circuit 2b and the incoming pulse 6 is taken at the logical product circuit 3 and specified pulse is picked up from the incoming pulse 6.
