Abstract

A system and method of damping the ringing response of Band Pass Filters for use in impulse and single cycle modulation systems which are capable of carrying a high data rate and which are severely affected by the ringing response of the Band Pass Filter.

Claims

1. A method of damping the ringing response of band pass filters for use in impulse and integer cycle modulation system transmitters and receivers comprising switching on and off at repeating intervals that are synchronized with an impulse signal and band pass filter propagation delays the ringing response of a band pass filter after said band pass filter receives an impulse signal such that only main lobes of said impulse signal remains and all unnecessary information between said main lobes is removed.

2. A system of damping the ringing response of band pass filters for use in impulse and single cycle modulation system transmitters and receivers comprising:

a switching device capable of turning on and off at the desired time the ringing response of a band pass filter after said band pass filter receives impulse inputs such that only main lobes of said impulse signal remains and all unnecessary information between said main lobes is removed; and

,

a timing device in electrical communication with and controlling said switching device and capable of generating timing pulses that are synchronized with the impulse signal and band pass filter propagation delays.

3. The system of claim 2 wherein said switching device is in series with and after all of said band pass filters.

4. The system of claim 2 wherein said switching device is in series with and after each of said band pass filters.

5. The system of claim 2 wherein said switching device is in parallel with all of said band pass filters.

6. The system of claim 2 wherein said switching device is in parallel with each of said band pass filters.

7. The system of claim 2 wherein said timing device is implemented in programmable logic circuits such that the system is software controlled and the propagation delay and pulse width of said timing pulses can easily be modified to match changes to the modulation system.
