by the use of resonant circuits

Full Title

Manipulating of pulses not covered by one of the other main groups of this subclass (circuits with regenerative action H03K3/00, H03K4/00; by the use of non-linear magnetic or dielectric devices H03K3/45) > Shaping pulses (discrimination against noise or interference H03K5/125) > by increasing duration; by decreasing duration > by the use of resonant circuits
