Input from f-m discriminator of ground receiver for neutron-detecting radiosonde contains two sub-carrier oscillator frequencies plus sleep un wanted pulses at audio blocking rate of 10 to 200 cps. Three-stage amplifier feeds amplified input signals to one-shot mvbr V3A-V3B for blocking of unwanted pulses. Out-put of gated amplifer V4 then contains only bursts of the two desired subcarrier frequencies.-L. Hillman and It. C. Haymes, Modifying a Telemetry System for Balloon-Borne Neutron Detection, Electronics, 34:11, p 60-63.
