Abstract:
1. A method of damping the ringing response of band pass filters for use in impulse and integer cycle modulation system transmitters comprising switching on and off at repeating intervals that are synchronized with a continuously generated impulse signal and band pass filter propagation delays, the ringing response generated from a band pass filter after said band pass filter receives said continuously generated impulse signal by opening the output of said band pass filter or filters, shunting the output to the input of said band pass filter or filters, or shunting the output of said band pass filter or filters to ground wherein said shunting is synchronized with said continuously generated impulse signal and band pass filter propagation delays, such that the in band ringing response of said band pass filters are removed and only main lobes of said impulse signal remains and all unnecessary in band information between said main lobes is removed resulting in narrow band transmissions.
