Time-domain gated filter for RF communication systems

摘要

A time domain filter receives a double sideband (DSB) input in the frequency domain and compresses this input into a time domain signal filtered by a time gate for providing a time filtered signal that is then expanded back into the frequency domain as a single sideband (SSB) output with one sideband being filtered by the time gate for translating DSB signals into SSB signals well suited for communicating chirped modulated signals as SSB signals along an electrical line or optical fiber without dispersive nulling of the communicated signal.
