摘要: A method and apparatus for frequency conversion comprising sampling an input signal having a first frequency with first time delays between samples in an input delay line, and distributing the samples of the input signal in sequence to an output delay line with different time delays between samples than the first time delays, to generate an output signal of different frequency than the input signal.

摘要: This invention relates to a system for storing a pulse modulated radio frequency signal and for accessing and reconstructing the stored signal repetitively whereby it can be retransmitted as desired, either at the same frequency or at a shifted or shifting frequency. An input delay line is sampled at a plurality of locations and the signal samples are stored by a plurality of capacitors. The capacitors are accessed at will and the stored samples are applied to locations on an output delay line similar to the input delay line, where the input signal is reconstructed.
