Signal delay device and simulator device for simulating spatial distances in distance measuring devices based on electromagnetic waves

Abstract

A signal delay device includes a demultiplexer, D∈delay means, D additional delay means, a multiplexer, and a control unit. For each delay means, a delay input and a demultiplexer output are connected, and a delay output and a multiplexer input are connected. For each additional delay means, an additional delay input is connected to a delay signal path, and an additional delay output and a multiplexer input are connected. The demultiplexer divides an input data word stream into parallel data word streams. Each delay means will delay the data words in the parallel data word streams. Each additional delay means will delay the data words in the delayed parallel data word stream by an additional delay time. The control unit controls the multiplexer such that an output data word stream corresponding to the input data word stream with a time delay is output.
