A digital technique is presented for compensation of time-base error in magnetic tape recorder data. A buffer shift register with feed¬back control is used to obtain a variable delay of the recorded signal during playback. A breadboard version is described and typical experi¬mental results are provided to demonstrate the performance of the system. A mathematical model of the system is developed and Justified by comparing analytical results with data from the breadboard model. The feasibility of the technique for airborne tape recorders is predicted based upon an estimate of system weight) size, and cost.
