ABSTRACT:
A digital linear interface system to interface between the output of a tape deck and a separate data input for each of n channels of data input. Each channel of the digital linear interface system consists of a high Q bandpass filter, a rectifier, a peak detector, and a phase locked loop demodulator. A light emitting diode connected between the rectifier and the phase locked loop demodulator lights when the bandpass filter is tuned to the center frequency. The system separates n linear sine waves having data stored on a separate sine wave for each channel.
