Abstract : Various band, blocking, and other filters made of LC or RC elements for the separation of the useful signal from a background of strong harmonic noise can be utilized with success only if the perturbation has a continuous character. The author gives a description of difficulties encountered with pulsed perturbations, and presents a brief description of the design and operation of the circuit capable of separating out brief signals from the background of pulsed perturbations exceeding the useful signal by 70 to 80 db. The use of a substraction circuit in conjunction with a low Q-factor RC filter results in a quality signal filtration in the presence of sharp radiopulse perturbations. (Author)
