BEAM FORMING SYSTEM HAVING LINEAR SAMPLERS

摘要

A frequency conversion circuit having a plurality of N signal channels, each being fed an input signal and a train of pluses having a period T and a duty cycle T/N. Each channel includes: a sampler coupled the input signal and being responsive to sampling signals; and a controllable time delay for producing the train of sampling signals in response to the train of pulses, the time delay imparting a time delay to the pulses in accordance with a time delay command signal fed to the time delay. Each one of the sampling signals is produced by the time delay in each one of the channels with the period T and the duty cycle T/N with the sampling signals in one of the to trains of the sampling signals being delayed with respect to the sampling signals in another one of the trains the sampling signals a time T/N.
