Abstract
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.
Claims23
Signal translation means comprising an input delay line means for distributing said signal, means for sampling the amplitude of the distributed signal at predetermined points along the delay line means, amplifier means for amplifying the samples taken at said predetermined points along the delay line means, means for storing the samples, output delay line means similar to the input delay line means, and means for applying the stored samples to the output delay line means at points corresponding to said predetermined points.
Signal translation means comprising:
- (a) an input delay line for distributing an input signal,
- (b) means for sampling the amplitude of said distributed signals at first predetermined points along the input delay line,
- (c) a plurality of analog memory means, each having a plurality of storage locations for storing a signal corresponding to the amplitude of said samples,
- (d) means for switching said samples from each said point to successive ones of said storage locations in sequence of corresponding analog memory means, at first predetermined times,
- (e) an output delay line similar to the input delay line for providing an output signal,
- (f) means for switching each of the storage locations of individual ones of said memory means to second predetermined points along the output delay line which correspond to said first predetermined points, at second predetermined times,
- whereby the input signal can be reconstituted in the output delay line.
Signal translation means comprising:
- (a) an input delay line for distributing an input signal,

- (d) first means for switching the samples from each said point to corresponding ones of capacitors,
- (e) an output delay line similar to the input delay line for providing an output signal,
- (f) output means for sampling and thereby connecting each of the memory means to said predetermined points along the output delay line which correspond to said first predetermined points,
- whereby the samples are applied to the output delay line for reconstituting the input signal therein.
Signal translation means comprising an input delay line means for distributing said signal, means for sampling the amplitude of the distributed signal at predetermined points along the input delay line means, means for storing the samples from said sampling means, output delay line means similar to said input delay line means, and means for applying samples stored by said storing means to the output delay line means at points corresponding to said predetermined points along said input delay line means.
